Which ratio describes the relationship if the number if gallons is compared to the number of quarts

maybe i can

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.

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
