The midpoint of segment AB is P(0, 4). If the coordinates of B are (-2, 3), then the coordinates of A are

A

(2, 5)

B

(-2, -5)

C

(2, 9)

D

(-2, 11)

Text Solution

Verified by Experts

The correct Answer is:
A

Let the point A be (a, b). Then,
`(a +(-2))/(2) = 0 "and" (b+3)/(2) = 4`
`rArr a -2 = 0 "and" b = 8-3 rArr a = 2, b = 5.`
`therefore ` the point A is (2, 5).
