Question

What is the distance between the points (-12, 11) and (-18, 17), to the
nearest tenth? *

Answer 1

8.5 units

Explanation:

The distance between two points is given by

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

Taking points (-12, 11) and (-18, 17) as the first and second points respectively then

`d=\sqrt{(-18--12)^(2)+(17-11)^(2)}`

`d=\sqrt {36+36}`

d=8.48528137423857 units

Rounded off to nearest tenths

d=8.5 units
