Answer:
The equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]
Step-by-step explanation:
We need to find an equation of the line that passes through the points (-6, -2) and (-3, 2)?
The equation of line in slope-intercept form is: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=-6,y_1=-2, x_2=-3, y_2=2[/tex]
Putting values and finding slope
[tex]Slope=\frac{2-(-2)}{-3-(-6)}\\Slope=\frac{2+2}{-3+6} \\Slope=\frac{4}{3}[/tex]
So, we get slope: [tex]m=\frac{4}{3}[/tex]
Finding y-intercept
Using point (-6,-2) and slope [tex]m=\frac{4}{3}[/tex] we can find y-intercept
[tex]y=mx+b\\-2=\frac{4}{3}(-6)+b\\-2=4(-2)+b\\-2=-8+b\\b=-2+8\\b=6[/tex]
So, we get y-intercept b= 6
Equation of required line
The equation of required line having slope [tex]m=\frac{4}{3}[/tex] and y-intercept b = 6 is
[tex]y=mx+b\\y=\frac{4}{3}x+6[/tex]
Now transforming in fully reduced form:
[tex]y=\frac{4x+6*3}{3} \\y=\frac{4x+18}{3} \\3y=4x+18\\4x-3y=-18[/tex]
So, the equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]

Answer:
1/2 minutes
Step-by-step explanation:
you add the two fractions together and because they have a common denominator you just add across.
1/8+3/8=4/8
now we simplify
the numerator and denominator can both be divided by 4.
4÷4=1
8÷4=2

If the radius is 21 cm and the angle at
center of circle is 140° then the length of
the arc is ?
Step-by-step explanation:
Given: Radius , r =21 cm
The angle at the center of the circle, n° =140°
Length of an arc =?
W.K.T Formula, Length of an arc = 2πr( n°÷360°) units
= 2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm
Answer:
2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm

a. (0, 4)
General Formulas and Concepts:
Algebra I
The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

The three angles of a triangle have
measures of 56°, (2x + 4)º, and xº
What are the measures of the three
angles of the triangle? (TEK 8.8D)
A. 56°, 80°, 44°
B. 56°, 90°, 34°
C. 56°, 84°, 40°
D. 56°, 60°, 64°
Answer:
56°, 84°, 40°
Step-by-step explanation:
The three angles of triangles have measures of 56°, (2x + 4)º, and xº.
We need to find the measures of the three angles of the triangle.
We know that, the sum of angles of triangle is equal to 180º. Using this property we get :
56°+ (2x + 4)º + xº =180º
Solving for x.
60 + 3x = 180
3x = 120
x = 40º
Other angle, = 2x+4
= 2(40)+4
= 80+4
= 84º
So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simplest form.
Answer:
1/5
Step-by-step explanation:
Equation: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Points: (-3, -9) and (22, -4)
[tex]y_{2}[/tex] is the second y point that shows up on the question, basically go by order. So it's -4
[tex]y_{1}[/tex] is -9, because again, in order of which coordinates pop-up first in the question
[tex]x_{2}[/tex] is 22, [tex]x_{1}[/tex] is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] = [tex]y_{2} - y_{1}[/tex] and [tex]x_{2} - x_{1}[/tex], we'll put them back in a fraction later
[tex]y_{2} - y_{1}[/tex] = -4 - (-9) = -4 + 9 = 5
[tex]x_{2} - x_{1}[/tex] = 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5
