Question

The distance between points A (-3, 8) and B (6,8) on the coordinate plane

is given by the expression |-3-6). Which is the distance between points
A and B?

Answer 1

The distance between the points is 9.

Explanation:

The co-ordinates of the given points shows that, the y-co ordinates of both the points are same.

It means that these points lie in the same horizontal line.

Hence, we just need to check the distance between the x co ordinates of the given points, to check the distance between the points A and B.

The distance between -3 and 6 is 6 - (-3) = 9.

Hence, the distance between A and B is 9.
