Here’s your shmoop du jour, brought to you by Line Segments.

The midpoint of AB is (1.5, 3). If A is (-0.5, 2), what is the x-coordinate of B?

00:21

Okay, so we’re asked to find the x-coordinate of the point that will create a line segment

00:26

whose midpoint is 1.5, 3.

00:29

All right… first, it helps to graph out the information we do have.

00:34

Since we’re just concerned with finding the x-coordinate, we only need to focus on

00:38

the x-coordinates of the problem.

00:40

To go from the x-coordinate of point A to the x-coordinate of the midpoint,

00:45

we need to hop over 2 units to the right.

00:48

Since it's the MIDPOINT, we know point B must have an

00:51

x-coordinate another 2 units to the right of the midpoint.

00:56

We have 1.5 plus 2 is 3.5...

01:00

That's it. That's our answer. 3.5.
