Expert Answer

Step 1

Given, a snowplow has maximum speed of 35 miles per hour on a dry highway. Its maximum speed decreases by 1.3 miles per hour for every inch of snow on the highway.

Here, the y-intercept c is 35 and the rate of change (slope) m is -1.3.

Step 2

A linear equation is of the form,

y = mx + c

So the equation that used to model this situation is,

y= -1.3x+35

Step 3

To find the depth that the snowplow wil...
