Question

Find the distance from Point A (4,2) to Point B (-3,2).

Answer 1

7

Explanation:

You can use the distance formula, but since both points have the same y-coordinate, they lie on a horizontal line. Just find the difference between the x-coordinates and take the absolute value.

distance = |-3 - 4| = |-7| = 7

Answer 2

The distance is:

`d=7`

Explanation:

The distance d between two points
`(x_1, y_1)` and
`(x_2, y_2)` is calculated using the following formula:

`d=√((x_2-x_1)^2 + (y_2-y_1)^2)`

In this case the points are:

A (4,2), B (-3,2).

Then the distance is:

`d=√(((-3)-4)^2 + (2-2)^2)`

`d=√(((-7)^2 + (0)^2)`

`d=√(49)`

`d=7`
