Laura is driving to seattle. suppose that the remaining distance to drive (in miles) is a linear function of her driving time (in minutes). when graphed, the function gives a line with a slope of -0.75 . see the figure below. laura has 51 miles remaining after 33 minutes of driving. how many miles were remaining after 15 minutes of driving?

Laura has 64.5 miles remaining after 15 minutes of driving.

Step-by-step explanation:

Laura is driving to Seattle. Suppose that the remaining distance to drive (in miles) is a linear function of her driving time (in minutes).

Slope of the function = -0.75

Laura has 51 miles remaining after 33 minutes of driving.  It means the the line passes through the point (33,51).

The point slope form of a line is

The equation of line is

Add 51 on both sides.

We need to find how many miles were remaining after 15 minutes of driving.

Substitute x=15 in the above equation.

Therefore, Laura has 64.5 miles remaining after 15 minutes of driving.

assuming you mean addition: addition and subtraction are reverse operations.
