Question

The midpoint of CD is E(-1, 0) One endpoint is C(5.2). What are the coordinates of the other endpoint?

Answer 1

The midpoint coordinates are: \[ \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)=(-1, 0)\]
You are given one point, say \((x_1, y_1)=(5, 2)\)

So for the x-coordinate of the midpoint, you can write the following:
\[ \frac{x_1+x_2}{2}=\frac{5+x_2}{2}=-1\]

For the y-coordinate midpoint, you have \[ \frac{y_1+y_2}{2}=\frac{2+y_2}{2}=0\]

Answer 2

can you solve for \(x_2\) and \(y_2\) in each case?

Answer 3

yes, thank you(:
