use the distance formula ...
plug in your known values and solve for the missing value of y ... note that you will get two solutions.
I have one homework question I can't seem to get it!! I'm looking for the answers thank you.
It says, Find all values of Y such that the distance between (9,y) and (-4,6) is 17.
Y=???
*(Use a comma to seperate answers as needed. Type exact answers, using radicals as needed.)*
THANK YOU SO MUCH
We use the distance formula to find the distance between two points:
Given the distance, a point (name it A), and the x-coordinate of another point (name it B), we can find the y-coordinate of B using the distance formula.
d = 17
A(-4,6) =
B(9, y) =
Solve for y now. I will complete the square.
EDIT: It's all good.
