Question

The midpoint of a line segment with end points as (x, 4) and (-2, -2) is (2, 1). What is the value of x?

x = 6

x = 4

x = -3

x = -2

Answer 1

\[midpoint=\left( \frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)\]
We know X1=-2, and the x-value of the midpoint is 2.
So, 2=(-2+X2)/2
--> 4=-2+X2
-> X2=6

Answer 2

Oh yeah, I forgot about doing that...

Answer 3

x=6
