Hoa sells vacuum cleaners. she earns $500 weekly salary in addition to $40 for each vacuum cleaner sold. write a linear equation to represent her weekly pay based on the number of vacuum cleaners she sells.

question 15 options:

y=40x+500

y=500x+40

x=40y+500

x=500y+40

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.
