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

The mean of \(x\) and -2 is 2.

Answer 2

The mean of two numbers \(a,b\) is \(\Large {a + b \over 2}\). Similarly, the mean of \(x\) and -2 is 2.

This may be represented as the follows \[ {x + (-2) \over 2} = 2\]

Answer 3

so the answer is -2 ?

Answer 4

No! Solve the equation.

Answer 5

can u do it @karamarie ???

Answer 6
