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?

Answer 1

x = -3
x = -2
x = 4
x = 6

Answer 2

The mid point of two points A(x,y0 and B(x',y') is given by M(A,B), where:
A = (x + x')/2
B = (y + y')/2

You have the values of x', y, y', A and B sated. Find out 'x'.
