Answer:

Explanation:

Slope is defined as the rate of change of one variable with respect to an other variable.

Let
be the distance travelled in
seconds.

Let
be the slope.

Then,
m=(d)/(t)

Given,

$d=800miles\\t=9hours$

So,
m=(800)/(9)

This slope is the rate of change of distance towards home for every hour travelled.

Let
be the distance from home.

(dD)/(dt)=m=(800)/(9)
