Find the distance between (-19, -17) and (-4, -9).

Question

Please help finding the distance

Answer 1

Distance = Square root of (y2-y1)^2 + (x2-x1)^2

Subtract the y on the left from the y on the right like this

-9 - -17 = -9 + 17 = 8

square that

8^2 = 64

Thats the (x2-x1)^2 part

Subtract the x on the left from the x on the right like this

-4 - -19 = -4 + 19 = 15

square that

15^2 = 225

That's the (y2-y1)^2 part

Using the formula distance = square root of (y2-y1)^2 + (x2-x1)^2 we now have

Distance = Sqrt(64+225)

Distance = Sqrt(289)

Distance = 17
