This table gives a few (x,y)(x,y)left parenthesis, x, comma, y, right parenthesis pairs of a line in the coordinate plane. -28 -
Serhud [2]

Answer:

The y-intercept is y = 2

Step-by-step explanation:

A linear function has the following format:

y = mx + b

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.

We are given these three points:

(-28, -54)

(-21, -40)

(-14, -26)

We use two of them to build a system, to find values for m and b.

(-28, -54)

This means that when x = -28, y = -54

So

y = mx + b

-54 = -28m + b

28m = b + 54

m = \frac{b + 54}{28}

(-21, -40)

This means that when x = -21, y = -40

So

y = mx + b

-40 = -21m + b

-40 = -21\frac{b + 54}{28} + b

-40 = \frac{-21b - 1134 + 28b}{28}

7b - 1134 = -40*28

7b = 14

b = \frac{14}{7}

b = 2

The y-intercept is y = 2

Write an equation of the line that passes through
Westkost [7]

Answer:

The answer is

<h2>y = - 8x + 8</h2>

Step-by-step explanation:

To find the equation of the line given a point and slope we use the formula

y - y _{1} = m(x - x _1)

where

m is the slope

( x1 , y1) is the point

From the question the point is

(1/2,4) and slope m = -8

The equation of the line is

y - 4 =  - 8(x -  \frac{1}{2} ) \\ y - 4 =  - 8x + 4 \\ y =  - 8x + 4 + 4

We have the final answer as

<h3>y = - 8x + 8</h3>

Hope this helps you
