Question

Let (2, 1) and (10, 4) be the coordinates of points A and B on the coordinate plane. What is the distance in units from points A to point B?

Answer 1

`"distance" = sqrt(73) ~~ 8.544` units

Explanation:

Given: `A(2, 1), B(10, 4)`. Find the distance from A to B.

Use the distance formula: `d = sqrt((y_2 - y_1)^2 + (x_2 - x_1)^2)`

`d = sqrt((4 - 1)^2 + (10 - 2)^2) = sqrt(3^2 + 8^2) = sqrt(73)`
