Question

A horizontal line segment has a midpoint of (4,2). If the length of the segment is 20 units, what are the coordinates of the endpoints of the segment?

Answer 1

First off, we know the line is horizontal that is that m=0, in this case the line y=2. Now we also know that the segment is 20 units long and the mid-point occurs at (4,2). as the line is horizontal all we need to do to find the end points is subtract half the length, 10, from the x cooridinate. In this case the end points are (-6,2) and (14,2)

Answer 2

Thank you so much!!!!
