Find the distance between points A and B if A (1; -2), B (4; -2).

In order to find the distance between points A (1; -2) and B (4; -2) we will use the following formula.

Let’s remember the formula for finding the distance between two points on a plane.

We are given two sinks with coordinates A (x1; y1) and b (x2; y2).

To find the distance between them, we use the formula:

AB = √ ((x2 – x1) ^ 2 + (y2 – y1) ^ 2);

Apply the formula and get the distance between the points with coordinates A (1; -2) and B (4; -2).

AB = √ ((4 – 1) ^ 2 + (-2 + 2) ^ 2) = √ (9 + 0) = √9 = 3.

Answer: the distance between the points is 3.
