Question

Can someone please tell me these answers

Answer 1

Answer:

4/5

Step-by-step explanation:

To find the rate of change, you are finding the slope of the chart.

Using the equation, △y/△x can be rewritten as $\frac{y2-y1}{x2-x1}$.

Plug in 2 coordinate points in the chart to find the rate of change.

$\frac{8-4}{10-5} =\frac{4}{5}$

The rate of change is 4/5.
