Help!!! Algebra 2 summer homework!!?
(3, 3/7), (4, -2/7)
I basically know how to do it, but the fractions are confusing me!
Favorite Answer
(4, -2/7) = (x2, y2)
distance formula = squareroot [(x2-x1)^2 + (y2-y1)^2]
D = sqrt [(4-3)^2 + (-2/7 – 3/7)^2]
D = sqrt [ 1^2 + (-5/7)^2]
D = sqrt [ 1 + 25/49]
D = sqrt [ 49/49 + 25/49 ]
D = sqrt [ 74/49]
D = sqrt [1.51]
D = 1.23
P.S. Even though you have fractions here… you still find the distance the same way as when you have all whole numbers. Don’t let the fractions confuse you… just pretend that they are whole numbers and find the distance using the same steps that you would use if you had, say, (3,2), (6,9)…. Okay? I know that you can do it… :o) yes, even when you have fractions…
If you had (3, -4) and (-6, -6)… you’re not going to let the ” – ” signs confuse you, right? You would use the same steps as if you had all positive coordinates, right? Same thing with fractions…
