Hi, i am from the UK and teaching myself A Level Maths (the equivilent of grades 11 and 12 in the US) and am having trouble with a question on coordinate geometry in my text book. It is as follows:
The equations of two sides of a square are y=3x-1 and x+3y-6=0. If (0,-1) is one vertex of the square find the coordinates of the other vertices.
So far i have solved the two line equations simultaneously to get a second vertex (9/10, 17/10) and then found the length of the line between the two sets coordinates i have, which is 9/10*sqrt(10)
Now i don't know how to use this length to find the other two coordinates or where to go from here.
any help?
thanks
