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

\[midpoint = \frac{x_1 + x_2}{2}\]
\[2 = \frac{-2 + x}{2}\]
\[4 = -2 + x\]
do you see it now?

Answer 2

6?

Answer 3

6 - -2 = 4 so the answer would be 6 right?

Answer 4

yup

Answer 5

6 is right

Answer 6

oh ha. that was simple. it was justy confusing to me because i thought there is suppose to only be 2 sets of numbers to do the formula

Answer 7

yup there is...but since you're only looking for x why make it difficult :)

Answer 8

the complete formula is \[\large midpoint = \frac{x_1 + x_2}{2} \quad , \quad \frac{y_1 + y_2}{2}\]

Answer 9

oh okay that makes sense now. thankyou :D
