Question

What is the distance between R(–5, 2) and S(4, –7)?

Round to the nearest tenth.

Answer 1

12.7

Explanation:

Answer 2

Using the distance formula:

d =
`√((x2-x1)^2 + (y2-y1)^2)`
d =
`√((4 - (-5)^2 + (-7 - 2)^2)`
d =
`√((9)^2 + (-9)^2)`
d =
`√(81 + 81)`
d =
`√(162)`
d = 12.7

Hope this helps :)
