What is the distance between (-13, 9) and (11, 2) on a coordinate grid?

Answer 1

25

Explanation:

You would use the distance formula.

d=

`\sqrt{(x1 - x2) {}^(2) + (y1 - y2) {}^(2) }`

plug in your numbers to get

`\sqrt{( - 13 - 11) {}^(2) + (9 - 2) {}^(2) }`

simplify down to get

`\sqrt{( - 24) {}^(2) + (7) {}^(2) }`

solve the squared to get

`√(576 + 49)`

add to get

`√(625)`

which equals

25

because 25 is the square root of 625

(25×25=625)
