Question

Given that a line is passing through points (6, 4), (12, 8), (-3, -2), (-6, -4), find the equation of this line.

Answer 1

Let points be A(−2,6),B(4,8),C(8,12) and D(x,24)

If two lines are perpendicular, then product of their slope is −1

So, Slope of AB× Slope of CD=−1 ...

We know that slope of a line through the ppoint
