Answer:  

y = -3 * x + 5

Step-by-step explanation:  

We start with the equation for slope-intercept y = mx + b -  

Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.  

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -  

(8 - (-1)) / ((-1) - 2)  

9 / (-3)  

Slope = -3  

Now we insert the slope into the equation -  

y = -3 * x + b  

As said before, Y is any y point on the line and X is any x point on the line, so we can choose a random point and insert it in to find the y-intercept -    

-1 = -3 * 2 + b  

-1 = -6 + b  

b = 5

The y-intercept of the line is (0, 5)  

We insert the y-intercept in the equation -  

y = -3 * x + 5  

y = -3 * x + 5 is our answer to the problem.

Answer:

The equation of a line in point-slope form is y-Y1=m(x-X1). ”m” is the slope and (X1,Y1) is a point.

So, the equation in point-slope form is y+5=12(x+4).

Answer:

$1.1

Step-by-step explanation:

[tex] \frac{100}{price \: before \: \: decrease \: (x)} \: = \frac{100 - 20}{0.88} [/tex]

[tex] \frac{100}{x} = \frac{80}{0.88} [/tex]

Cross multiply

80x = 88

X = 88/80

X = 1.1

the cost of one liter of fuel in May 2014 was $1.10.

Let's denote the cost of one liter of fuel in May 2014 as "x" dollars.

According to the information given, the cost of one liter of fuel in May 2015 was a decrease of 20% on the cost in May 2014. This means that the cost in May 2015 was 80% of the cost in May 2014.

Mathematically, we can express this as:

Cost in May 2015 = (100% - 20%) * Cost in May 2014

0.88 = 0.8 * x

Now, let's solve for "x" (the cost in May 2014):

x = 0.88 / 0.8

x = 1.10

So, the cost of one liter of fuel in May 2014 was $1.10.

Answer:

2nd option

Step-by-step explanation:

given a quadratic in standard form

y = ax² + bx + c

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here a = - 1 < 0 then maximum

The maximum value is the value of the y- coordinate of the vertex

The x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

Here a = - 1 and b = 3 , then

x = - [tex]\frac{3}{-2}[/tex] = [tex]\frac{3}{2}[/tex]

Substitute this value into the equation for corresponding y- value

y = - ([tex]\frac{3}{2}[/tex] )² + 3([tex]\frac{3}{2}[/tex] ) - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{9}{2}[/tex] - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{18}{4}[/tex] - [tex]\frac{4}{4}[/tex] = [tex]\frac{5}{4}[/tex]

Then maximum value of [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

slope:-1/2

y-intercept:1   (because the function passes (0,1))

The slope of the linear function is -2 and the y-intercept is 2. Therefore, the correct answer is: slope: -2; y-intercept: 2.

A linear function is a type of function where the rate of change of the dependent variable (y) with respect to the independent variable (x) is constant. In other words, the graph of a linear function is a straight line.

To determine the slope and y-intercept of the linear function graphed, we can use the slope-intercept form of a linear equation, which is:

y = mx + b

Where m is the slope and b is the y-intercept.

Looking at the graph, we can see that the line passes through the y-axis at the point (0, 2), which means that the y-intercept is 2. To find the slope, we can choose any two points on the line and use the formula:

slope = (change in y) / (change in x)

For example, we can choose the points (-1, 0) and (1, -4) which lie on the line. The change in y is -4 - 0 = -4, and the change in x is 1 - (-1) = 2. Therefore, the slope is:

slope = (change in y) / (change in x) = -4 / 2 = -2

Hence, the slope of the linear function is -2 and the y-intercept is 2. Therefore, the correct answer is:

slope: -2; y-intercept: 2

Thus, the answer is slope: -2; y-intercept: 2.

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Equations of lines that are perpendicular have gradients that are negative reciprocals of each other. This means that the gradient of one of the lines is negative 1 times the fraction flipped.

With the equations presented in the form y = mx + c, the gradient is m. This means you need to look for the values of m where one is the negative reciprocal of the other.

In C, the first gradient is 6/11. The reciprocal (flipped) is 11/6. Make this negative and you get -11/6, which is the gradient of the second equation, so these lines are perpendicular.

Substitute all the given numbers into the equation, by doing so this should give you 2x-1+3x+2+x^2.

Since we have a group of x’s add them together, which would make 6x^2, this leaves our -1 and +2 add these these two numbers together to make plus one and finally you will have 6x^2+1

Find the slope of the parallel line

When two lines are parallel, they have the same slope.

                ⇒  if the slope of this line = 1

                     then the slope of the parallel line (m) = 1

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  (5, 4)  

                              ⇒  y - 4 = 1 (x - 5)                                

                                ∴  y - 4  = x - 5

We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:

                     since    y - 4 = x - 5
