Question

Find the rate of change of this line

Answer 1

I picked two points in the graph, (-1, 0) and (1, 1).

Find the rate by solving for the slope (rise / run).

Rise = x₂ - x₁ = 1 - (-1) = 2

Run = y₂ - y₁ = 1 - 0 = 1

Slope = 2 / 1 = 2

The rate is m = 2

Answer 2

the slope/rate of change is m=2
