Question

What is the distance between (-8, -1) and (-4, -9)?​

Answer 1

The distance formula between two points is

D=√(
`x_(2) \\` -
`x_(1\\)`)^2 + (
`y_(2)`-
`y_(1)`)^2

Whereas

d is distance

So in this case

(-8, -1)

(-4, -9)

x2 is -4

x1 is -8

y2 is -9

y1 is -1

Now we plug them in

d= √(-4 + 8)^2 + (-9+1)^2

Now solve

it’s about
