Question

Find all y such that the distance between the points (-6, -9) and (-4, y) is 28.

Answer 1

Should you try Pythagorean's theorem?

Answer 2

Nope, use the distance formula.

Answer 3

Like @steve816 said,use the distance formula :)

Answer 4

Your distance formula is Pythagorean's...

Answer 5

i did but i got sqrt y^2+18y+85=28. do i square both sides?

Answer 6

Answer 7

A^2+B^2=C^2 where C is your distance
Let a be x and b be y
(-6- -4)^2+(-9 + y)^2= 28^2
You will have 2 answers for y.
You could also graph it by hand...use a compass...radius=28
