Determine the rate of change from the table of solutions. determine the y-intercept from the table. write the equation of the line. x y -3 10 -2 7 -1 4 0 1 1 -2 2 -5 show your work ! will give

Pick two points at random so we can find the slope. I picked (0, 1) and (- 1, 4)

Slope = 

(4 - 1) / (- 1 - 0)
3 / - 1
- 3 is the slope.

Now plug this into slope-intercept form y = mx + b

y = - 3x + b

Use either of the points to find the b variable

1 = - 3(0) + b
1 = 0 + b
1 = b

Your equation is y = - 3x + 1

Rate of change is the same as slope so your rate of change is - 3. 

The y-intercept is the "b" in slope-intercept form so your y-int is 1. 

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
