Answer: You must switch all your letters and numbers around... to where your problem is y=-2x+2. Than after you get your answer, for the problem, Graph it... to graph it, you would take your b (+2) and find it on the graph, than you would take your m (-2) and find it on the graph, but! you must make sure it is a fraction so you will have to find two numbers and graph your second number, than make a STRAIGHT line on your point, all the way across your graph.

2x+3 = 7 2x = 7-3 2x = 4 x = 2
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
(2,-2)
x = (P - 2W) / 2
If we assume that it equals zero and you wish to solve for x, then the answer is:-x2 + 2x - 3 = 0x2 - 2x + 3 = 0x2 -2x + 1 = -2(x - 1)2 = -2x - 1 = ± √(-2)x = 1 ± i√2
