Aplant is 20 inches tall. if the plant grows 2h inches each week for the next 4 weeks, and h inches for each of the 2 weeks after that, which expression shows the height of the plant in inches after 6 weeks

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.

the correct answer is 1.7
