Question

Find the distance between the points A(2, 3) and B(4, 1).​

Answer 1

sqrt(8) units

Explanation:

Use the formula d=sqrt((x2-x1)^2 + (y2-y1)^2). d=distance, and (x1, y1) and (x2, y2) are the points.

d=sqrt((4-2)^2 + (1-3)^2)

=sqrt(2^2 + (-2)^2)

=sqrt(4+4)

=sqrt(8)

A and B are sqrt(8) units apart.

Answer 2

sqrt(8) or 2.828

Explanation:

You use the distance formula which is sqrt((x2-x1)^2+(y2-y1)^2) where x2 can be either x value
