Question

find the midpoint of the line segment joining the points R(1,3) and S(-2,6).

Answer 1

We have the points R(1,3) and S(-2,6).

We have to calculate the mid point.

The mid point will have coordinates that are the average of each point's coordinate.

In this case, being M the mid point, the coordinate X will be:

$M_x=\frac{R_x+S_x}{2}=\frac{1+(-2)}{2}=-\frac{1}{2}$

The Y coordinate will be:

$M_y=\frac{R_y+S_y}{2}=\frac{3+6}{2}=\frac{9}{2}$

The midpoint between R and S is M=(-1/2, 9/2).
