Question

Find the distance between the points (-9,-7) and (2,-6)

Answer 1

To solve this problem, we need to use the distance formula.

Distance =
`√((x2 - x1)^2 + (y2 - y1)^2)`

x1 = -9

x2 = 2

y1 = -7

y2 = -6

Plug your numbers in

Distance =
`√(((2) - (-9))^2 + ((-6) - (-7))^2)`. Simplify each parenthesis.

Distance =
`√(121 + 1)`. Add these numbers together and take the square root.

Distance = √(122) or 11.05 units.

Answer 2

`√(122)`

subtract the x from the other x and the y from the other y. Put that equation in a square root.
