Analytical Geometry Problem

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

Go get the formula for x_midpoint and substitute -7 in as x₁ and -1 as x_midpoint then solve for x₂ (other endpoint).

 

Repeat with appropriate y values in formula for y_midpoint
