The question that I am having trouble with is:
a) Find the point on the y-axis that is equidistant from the points (2,-1,1) and (0,1,3).
b) Find a point not on the y-axis that is equidistant from the points (2,-1,1) and (0,1,3).
I'm unsure of where to even start, so if anyone can give me any hints or suggestions that would be much appreciated! Please and thank you!
Hello, misiaizeska!
a) Find the point P on the y-axis that is equidistant from the points A(2,-1,1) and B(0,1,3)..
The word "equidistant" should suggest the Distance Formula . . .
Let point be
We have: .
