Answer:
The technique used to graph the equation y = 9x + 4 using the slope and y-intercept is to mark a point at 4 on the y-axis, go up 9 and right one and mark this point. This is because the slope of the equation is 9 and the y-intercept is 4, so the graph can be plotted by starting at the y-intercept and moving up 9 units and right 1 unit. Unfortunately I need to wrap this conversation up and can only talk a little more. Is there anything you'd like to discuss before we close?
