Verified answer

The answer I got was 21.6333, so Ill go with 21.6. But you should learn this and not ask for help on every question of your homework.

The formula is d=√[(x2-x1)^2+(y2-Y1)^2]

x2=-12 x1=6 y1= 5 y2=17

So √[(-12-6)^2 + (17-5)^2]

√[-18^2 + 12^2]

√[324+144]

21.633308

Answer is 21.6

√[468]

the distance between 2 points is: d=[ (x2-x1)^2 + (y2-y1)^2 ]^1/2

so, you just plug in the numbers to get d=[ (-12-6)^2 + (17-5)^2 ]^1/2

d=21.6

it actually doesn't matter if you do x2-x1 or x1-x2, but you need to be consistent with the y's as well.
