For this case we must find the solution of the following quadratic equation:

Where:

Then, the solution is given by:

Substituting the values:

Thus, we have two equal real roots.

We have two equal real roots.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

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.
