Step-by-step explanation:

See attachment for complete question

Given

Malcom's Family:

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

First, we determine the slope, m:

Next, we determine equation for Theo's family using:

Add 50 to both sides

So, we have the following:

--- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

--- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

Which implies that Malcom's family travel 15 miles per hour faster than Theo's
