Consider the table. Explain how to use a graph to find additional equivalent ratios.

A 2-column table with 2 rows. Column 1 is labeled Books (x) with entries 2, 4. Column 2 is labeled Cost (y) with entries 5, 10.

The explanation regarding the graph should be explained below:

The following information should be considered:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
