Step-by-step explanation:
since the coefficient is the same for the fist three they have the same equation.
the reason: there can only be one line that goes through one point with a specific coefficient.
Since we have 2 x values given:
You would need to look into the graph.
As x = 0, y = -1
As x = 2, y = 5
We have 2 coordinate points now YAY!
(0, -1) and (2, 5)
we next find the slope..... using the slope formula if you recall (Hint:
)

3 is your average rate of change from x = 0 to x = 2
