Endpoints and Segments

Question

One endpoint of a line segment is (-7, 2). The midpoint of the line segment is (-1, -2). What are the co-ordinates of the other endpoint?

Answer 1

You have, I trust, formulas for x_midpt and y_midpt

You know x₁ and x_midpt so substitute into them & solve for x_2.

Make a similar move relative to the y's to solve for y₂
