Question

Find the distance between the two points rounding to the nearest tenth (if necessary). (8,−4) and (−1,−2)

Answer 1

9.2 units

Explanation:

You want to know the distance between the two points (8,−4) and (−1,−2).

Distance formula

The distance between points (x1, y1) and (x2, y2) can be found using the distance formula.

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

Application

Using the given point coordinates, we find the distance to be ...

`d=√((-1-8)^2+(-2-(-4))^2)=√((-9)^2+2^2)=√(85)`

A calculator tells you this value is about 9.22.

The distance is about 9.2 units.
