I need some assistance on a question could someone please help?
Here is the question in the book.
Do the points (3, -4) (18, 6) and (9, 0) all lie on the same line? If so what is the equation of the line.
I looked in the answer section the answer is yes and the equation is 2x-3y=18
I do not know how to work the three points into the equation and I can't find any solutions in the book to help me.
Thank's for the help.
Mark
