Learn how to use the midpoint formula to find the midpoint of a line segment on the coordinate plane, or find the endpoint of a line segment given one point and the midpoint.

What problems can I solve with the midpoint formula? Given two points on the plane, you can find their midpoint. For example, let's find the midpoint of (5, 3) and (1, 7) :

In surveys or data analysis, finding the midpoint between two values can help figure out trends or create averages. It’s basically the “let’s split this thing evenly” tool for real life.

Approximating area under a curve using rectangle where the heights are the value of the function at the midpoint of each interval.

Find the midpoint of a segment on the coordinate plane, or find the endpoint of a segment given one point and the midpoint.

Given an information about the distance of a segment's midpoint from its endpoints, Sal forms and solves an equation in order to find the length of the segment. Created by Sal Khan.

Now another term that you'll see associated with the parabola, and once again, in the future, we'll learn how to calculate these things and find them precisely, is the vertex.

For this problem, we can just count the unit squares for each rectangle, but in general we'd need to multiply heights and widths to find area.
