Question

Find the rate of change demonstrated in the graph below.

Answer 1

The rate of change of a graph, is the slope of the graph.

The rate of change of the graph is 4.5

The points on the graph are:

$\mathbf{(x,y) = (2,9) (4,18)}$

So, the slope (m) is calculated as:

$\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}$

This gives

$\mathbf{m = \frac{18 - 9}{4-2}}$

$\mathbf{m = \frac{9}{2}}$

$\mathbf{m = 4.5}$

Hence, the rate of change of the graph is 4.5
