Question

A scale drawing of a storage box on a coordinate grid shows a square with the points (3, -1) and (4, 4) as the locations of two adjacent vertices.

Which pair of coordinate points could represent the other two vertices?

(-2, 0) and (-1, 5)

(8, -2) and (10, 3)

(-2, 0) and (8, -2)

(8, -2) and (9, 4)

Answer 1

They tell you that this is a square, meaning that all sides have equal length. Using the midpoint formula again you can set the coordinates you know equal to one of the sets given and calculate.

Answer 2

So the midpoint of (3,-1) and (4,4) should be equal to one of those other pairs.

Answer 3

okay hold on

Answer 4

a?

Answer 5

Yes. Sorry for the delay, I had to calculate it and some interruptions here.

Answer 6

Wait a sec, I might have dropped a sign. The trouble with distractions.

Answer 7

Nope, all good. :)
