Asked by John

I have a question that does not make sense to me and would like some help with it. I don't need the answer, only the way to solve.

It gives me a graph and asks me "what points would partition XY into segments with lengths having a ratio of 3:4?"

I can't share a grid, but here are the coordinates.

X = (-7), 12
Y= 7, -9

I'm just confused on the process of these questions, and I apologize to keep having to ask for answers on this site, but I can't reach any teachers due to the corona-virus outbreak in my area.

Thanks in advance :)

3 + 4 = 7 ... just divide the line into seven e

I'm not sure what you mean? Please explain

You have two points: (-7,12) and (7,-9)
x changes from -7 to 7, or 14
y changes from 12 to -9, or -21
You want a point P that is 3/7 of the way from X to Y. So,
P = X + 3/7 (Y-X) = (-7,12) + 3/7 (14,-21) = (-7,12)+(6,-9) = (-1,3)
