Find the midpoint of the segment joining A(-7, 4) and B(3, -8).

Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

Find the midpoint of the segment joining $A(-7, 4)$ and $B(3, -8)$ .

Need a reminder? The key ideaShow

The point dividing the line from $(x_1, y_1)$ to $(x_2, y_2)$ in the ratio $m : n$ is $\left(\dfrac{m x_2 + n x_1}{m + n}, \dfrac{m y_2 + n y_1}{m + n}\right)$ . The midpoint is the average of the two points.

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
