You plant an 8 inch tall tomato plant that grows 5 inches taller each week. On the same day, you plant a 14 inch tall tomato plant that grows 3.5 inches taller each week. Graph a system of equations that represents the height y (in inches) of the plants after x weeks. Use a graph to solve the system.

answer:

You plant an 8-inch-tall tomato plant that grows 5 inches taller each week. On the same day, you plant a 14-inch-tall tomato plant that grows 3.5 inches taller each week. Graph a system of equations that represents the heights y (in inches) of the plants after x weeks. Use the graph to solve the system.

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.
