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.
A linear equation is of the form,
y = mx + c
So the equation that used to model this situation is,
To find the depth that the snowplow wil...
