x = - 
x =
Answer: first step is \frac{2}{3}x\frac{1}{3}+2
Step-by-step explanation:
The rate of change is also known as the slope. To easily find the slope of a line, put the equation into slope intercept form by isolating y on one side.
8 + y = 2x
y = 2x - 8
By definition, the rate of change is 2.
