Calculating Rate of change

ivolga24 [154]

Answer/Step-by-step explanation:

We are given the following coordinates of two points on the line of the graph shown in the question as: A(2, 1) and B(4, 2)

Vertical change from point A = $y_2 - y_1 = 2 - 1 = 1$

Horizontal change from point A = $x_2 - x_1 = 4 - 2 = 2$

Rate of change = $\frac{y_2 - y_1}{x_2 - x_1} = \frac{1}{2} = 0.5$
