Question

What is the distance between 4,2 and 1,-2

Answer 1

Answer: 5

Explanation:

The formula for finding distance is
`d=\sqrt{(x_(2)-x_(1))^(2) +(y_(2)-y_(1) )^2 }`.

First, we plug in the values:

`d=√((1-4)^2+(-2-2)^2)`

Now, we solve what is in the parentheses (remember P.E.M.D.A.S):

`d=√((-3)^2+(-4)^2)`

Then exponents:

`d=√(9+16)`

Add everything up:

`d=√(25)`

Finally, find the square root:

`√(25)=5`

We now have our answer:

d = 5
