x = 6

x = 4

x = -3

x = -2

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

anonymous · Answer

Start with the midpoint formula.

Since we want to find the x-coordinate of the first point, we can set it up just like this...

(x+(-2))/2=2

anonymous · Answer

Solving that equation, we get 

x-2=4
x=6
