Question

A polygon has the following coordinates: A(-5,5), B(2,5), C(-5,-2). Find the length of AB.

A.
5 units
B.
7 units
C.
6 units
D.
4 units

Answer 1

7

Explanation:

Since these two points are straight left and right from each other it's really easy. Think of it as just moving so many spaces left or right on the x axis. We are moving from point (-5,5) along the line y=5 to the point (2,5), which is moving 7 units.
