Question

The points (-1,-5) and (6, -5) are on a coordinate plane. What is the distance between the points?

Answer 1

7

Explanation:

the x-coordinates are -1 and 6. there's a distance of 7 between those two.

the y-coordinates are -5 and -5. there's a distance of 0 between those two.

(distance between points)² = 7² + 0² = 49 + 0 = 49.

take the square root of both sides:

distance between points = √49 = 7.

this would also have worked if the y-coordinates were different.
