The chart below shows the number of miles driven and the gallons used. Make a scatter plot of the data. Label the graph. Draw a trend line

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

this is a tricky question, lol,   but i think the answer is 100,000.

the answer is  

c.

90.0π cm^2

hope you got it.
