Question : 24

Total: 50

Solution:

Concept:

The midpoint of two points is found by averaging the corresponding coordinates.

Explanation:

For points

P(x, 4)

and

Q(10, 8)

, the midpoint is given as

(9, 6)

The

x

-coordinate of the midpoint is:

\frac{x + 10}{2} = 9

Multiply both sides by

2

x + 10 = 18

Subtract

10

from both sides:

x = 8

Answer:

x = 8

, so the correct option is C. 8.
