The solution to a system of equations is 1, 5. Choose two equations that might make up the system.

Use the sketch tool if it helps you with your thinking.
y=-3x-6
y=2x+3
y=7x+1
y=x+4
y=-2x-9

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.
