Question

Indicate the equation of the given line in standard form.

The line containing the altitude to the hypotenuse of a right triangle whose vertices are P(-1, 1), Q(3, 5), and R(5, -5).

Answer 1

First step, plot these points. Have you plotted them?

Answer 2

if you plot the points, the hypotenuse becomes more obvious.
then find the slope of the hypotenuse

post it when you get it.
