Question

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

Answer 1

Answer:

The distance is:

$d=7$

Step-by-step explanation:

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

$d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$

In this case the points are:

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

Then the distance is:

$d=\sqrt{((-3)-4)^2 + (2-2)^2}$

$d=\sqrt{((-7)^2 + (0)^2}$

$d=\sqrt{49}$

$d=7$

Answer 2

Answer:

7

Step-by-step 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
