$y - 2 = 3 x$ , $(0, 3)$ , $(- 3, 0)$

Step 1

Write $y = 3 x + 2$ as a function.

$f (x) = 3 x + 2$

Step 2

Add $2$ to both sides of the equation.

$y = 3 x + 2$

Step 3

The first point $(0, 3)$ does not fall on the graph. The points must be on the graph to be able to calculate the average rate of change between them.
