Question

P, M, and Q are three points on a line. The coordinates of P and M are -6.9 and 3.4, respectively. If M is the midpoint of PQ, what is the coordinate of Q?

A) -1.75 B) 10.3 C) -3.5 D) 13.7

Answer 1

know the midpoint formula?

Answer 2

so.. M is the mid-point
so, recall your mid-point formula?

Answer 3

It would be B

Answer 4

Wait!!!! It would be D

Answer 5

The difference between points P and M is 10.3 so add 10.3 to the midpoint (3.4) and you would get 13.7.

Answer 6

Do you understand now?

Answer 7

jdoe0001 was wrong. This problem does not involve coordinate points so you do not use the midpoint formula.

Answer 8

I mean, it does it does involve coordinates, just not the (x,y) ones ya know what I mean right?

Answer 9

thank you

Answer 10

your welcome :)

Answer 11

I do understand now thanks

Answer 12

that's good. Do you need help with any other things?
