There are three points on a coordinate plane. They are at (7,2), (7,4), (-4,2) If these points were to make a rectangle, what would a fourth

Based on this....does happy7's answer seem to make sense ???

Hello anon user!

To make a rectangle,  there would need to be 2 pairs of the same coordinate on the x-axis and 2 pairs of the same coordinate on the y-axis.  (if that makes sense)

The coordinates for the x-axis:7,-4  There need to be two of each of these

The coordinates for the y-axis:2,4   There need to be two of each of these

From the first three points,  there were two 7's (for the x-axis) and two 2's (for the y-axis)

To make a coordinate,  you go from the x-axis location to y-axis location

Missing x-axis location:-4

Missing y-axis location:4

So the missing coordinate would be (-4,4),  to make a rectangle of (7,2), (7,4), (-4,2) and (-4,4)

I hope I helped you anon!
