What do I do I need help

y = -3x + 8

Step-by-step explanation:

This looks like it's in slope-intercept form.

So, they want you to write it like y=mx+b, where m is the slope and b is the y-intercept.

First, find the slope.

The slope is calculated by using:

You have several points. Let's use (1,5) and (2,2)

= 2

= 5

= 2

= 1

= = -3

The slope (m) is -3.

y = -3x + b

Now, find the y-intercept.

Substitute points in for y and x.

Let's use (1,5) (x,y)

x= 1

y=5

5= -3(1) +b

5 = -3 + b

b = 8

Add b to your equation.

y = -3x + 8
