A few questions regarding Linear Equations.
Q1) "▲LMN has vertices L(-1,2) and M(-4,-1).
a) Find the coordinates of N such that ▲LMN is a right triangle.
b) Is there more than one solution? Explain."
So, basically, it's telling me to find the coordinates of N, and that one of the angles is 90 degrees/perpendicular.
Q2) "A and k are one-digit numbers. Given two lines, Ax - 3y + 15 = 0 and y = kx + 7, determine the values of A and k if the two lines are:
To be honest, I don't understand this question at all...
