Question

If Point M has a coordinate of -1 and MN = 7, what are the possible coordinates of point N?

Answer 1

-8 and 6

Explanation:

Coordinate of point M = -1

Distance between M and a point N = MN = 7

Therefore, the possible coordinates of N can either be:

To the left => -1 - 7 = -8

Or

To the right => -1 + 7 = 6

Check:

If M = -1, and N = -8, MN = |-1 -(-8)| = |-1 + 8| = 7

Or

If M = -1, and N = 6, MN = |-1 - 6| = |-7| = 7

So, our answer is right.

Possible coordinates of point N are -8 and 6
