Find the equation of a line containing the given points. Write the equation in slope-intercept form.
y = ?
Answers
Answer:
y = x + 1
Step-by-step explanation:
(2,3) (-2, -1)
line equation y - y1 = m (x - x1)
m = (-1 -3) / (-2 - 2)
= -4 / -4 = 1
y - 3 = 1 * (x - 2)
y = x -2 +3
y = x + 1
Answer:
y = 1x+1
Step-by-step explanation:
Slope-intercept form is: y=mx+b
In order to find the slope, or "m" in this formula with two given points, use the slope formula for two coordinates: m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. In this formula, y2 is the second coordinate's y value, y1 is the first coordinate's y-value, and likewise x2 is the second coordinate's x value, x1 is the first coordinate's x-value.
In this problem specifically, we were given coordinates (2,3) and (-2,-1).
This is how those above values would line up:
y2 = -1
x2 = -2
y1 = 3
x1 = 2
Once this is plugged into the formula it becomes [tex]\frac{-1-3}{-2-2}[/tex] , which simplifies to a slope (m) of 1.
____________________________________________________________
Next to find the y-intercept, or "b" we simply need to plug in a coordinate's values into the slope-intercept form, and I chose (2,3) for simplicity's sake.
This would become (3) = 1(2) + b. Then just solve for b using algebra, which results in a b value of 1.
The answer is y= 1x +1 which can alternatively be written as y=x+1

At the movies, you order 3 boxes of popcorn and a bottle of water. The cost of the bottle of water is $1.75. Your total cost is $9.25. Write an EQUATION to find the cost of one box of popcorn.
Answers
A bottle of water is $1.75
$9.25 - $1.75 = $7.5 (the price of 3 boxes of popcorn)
We divide $7.5 by 3 to know the price of one box of popcorn
$7.5 : 3 = $2.5
One box of popcorn costs $2.5
Answer:
Step-by-step explanation:
$9.25-$1.75=7.5
now you divide 7.5 by the number of popcorn have brought
$7.5 divided by 3= $2.5
Gerard is calculating the area of a composite figure. The figure is made up of a square with side lengths of 6 centimeters (cm) and a triangle with a base of 6 cm and a height of 3.5 cm.
Gerard multiplies 6 by 3.5 to get that the area of the figure is 21 cm2, which is not the correct area.
Which statement correctly describes how Gerard could have found the correct answer?
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 27 cm2, to get 63 sq. cm.
-He should have added 6 to 3.5 to get 9.5 sq. cm.
-He should have multiplied 21 by 12 to get 10.5 sq. cm.
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 10.5 cm2, to get 46.5 sq. cm.

Answers
The correct statement is Gerard should have found the area of the square, 36 cm², and added it to the area of the triangle, 10.5 cm², to get 46.5 sq. cm.
What is Area?Area of a geometrical shape or figure in two dimension is the space which lies within the boundary of the shape.
The given composite figure composed of a triangle and a square.
So, we should find the area of both the triangle and the square and add it to get the area of the composite figure.
Let A₁ and A₂ be the area of the square and area of the triangle respectively.
Area of a square with side lengths 'a' = a²
Here, length of the side of the square = 6 cm
A₁ = 6² = 36 cm²
Area of a triangle with base 'b' and height 'h' = [tex]\frac{1}{2}[/tex] × b × h
Here, b = 6 cm and h = 3.5 cm
A₂ = [tex]\frac{1}{2}[/tex] × 6 × 3.5 = 10.5 cm²
Area of the composite figure = A₁ + A₂
= 36 cm² + 10.5 cm²
= 46.5 cm²
Hence Gerard could have found the correct answer by finding the area of the square as 36 cm², and adding it to the area of the triangle, 10.5 cm², to get the area of the figure as 46.5 cm².

y = ?
Answers
Answer:
Y=x
Step-by-step explanation:
Hope this helps you!
Answer:
y = x + 8
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of 1, and contains the point (-4, 4).
We want to write the equation of this line in slope-intercept form.
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept (hence the name).
SolvingSince we already are given the slope of the line, we can immediately plug it into the equation.
Substitute m as 1 in y=mx+b.
y = x + b
We now need to find b.
As the equation passes through (-4, 4), we can use its values to help solve for b.
Substitute -4 as x and 4 as y.
4 = -4 + b
Add 4 to both sides.
4 = -4 + b
+4 +4
_________________
8 = b
Substitute 8 as b in the equation.
y = x + 8

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The coordinates from the graph:
(2, 1), (3, 1.5), (4, 2), (6, 3), and (8, 4)
Where the x-axis is the number of months and the y-axis is the length of the hair in inches.
Now,
1 inch = 2.54 cm
3 inches = 3 x 2.54 = 7.62 cm
The hair length after 6 months.
= (6, 3)
= 3 inches
= 7.62 cm
Now,
6 months = 3 inches
Multiply 8/3 on both sides.
8/3 x 6 months = 8 inches
16 months = 8 inches
Now,
From the graph, we see that,
(8, 4)
This means,
In 4 months the length of the hair is 4 inches.
8 months = 4 inches
Multiply 5 on both sides.
40 months = 20 inches
Thus,
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.
