Point is x and y-coordinates have different signs(one is positive and the other is negative). neither coordinate is 0. where could e be located on the coordinate plane?

so then what are you asking?

step-by-step explanation:

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.

apex answer is: true.
