You can think of a line as a set of points (x,y) which satisfy an equation in the form of y = mx + d. Hence all the points (x,y) which satisfy that equation are on the line, all the points which don't aren't. First I'll transform this equation into the form y = mx + d, because it will be a bit nicer to use for this particular problem: y  3 = 5(x9)  + 3 y = 5x  45 + 3 y = 5x  42 Now for example, to see if A = (3,9) is on the line, you substitute x = 3 and y = 9 into that equation and if you' get a true statement, you know it's on the line, otherwise it isn't. 9 = 5*3  42 9 = 15  42 = 27 false! Hence A is not on the line.
