Nothing follows.


It is not fair to pose a problem in this way.

This is one point (x,y) x for time in hours, y for how high above sea level in miles.

One point from description is (0,1)
and slope is 1.5 miles per hour.

Since this is for a linear function
y=1.5x%2B1 in slope-intercept form.
You can call the function any other name you want to instead of y.
