The number in front of the "x" is the slope. That means the slope of "y=-3x+2" is "-3." The easiest way to plot a line through specific points is to graph the points on a quadratic plane. Connect those 2 points and follow the pattern of rise%2Frun. Lets say to get to point A, you have to go up 4 units and to the right 2 units. That means your slope would be 4%2F2 which simplifies to 2. So if you graph the points (-1,5) and (1,3)....your equation should be y=-x%2B4. "-x" because you go up one unit and to the left one unit. If you go to the left then it becomes negative. And it's +4 because the line crosses over the y-axis at +4.
