Distance = √(x2 − x1)^2 + (y2 − y1)^2
Substitute in the coordinates.
Distance = √(3 − (-7))^2 + ((-4) − 5)^2
Simplify by using order of operations/PEMDAS.
Distance = √(10)^2 + (-9)^2
Distance = √100 + 81
Distance = √181
The distance is √181 or 13.45362. However, I suggest leaving the distance as √181.
