Question 207624
When graphing, you do not need to plug in numbers. You just need to make sure the problem is in y=mx+b format. m is the slope of the line, while b is the y-intercept. Let's take the problem y=2x+3. You take the graph and place your first point at (0,3) for that is your y-intercept. You take the slope, 2/1 for that is the same as 2, and move up 2 spaces and right 1 space. Make a point at that spot. Draw your line through the two points. Do the same with the second equation, using (0,5) for the y-intercept and 1/1 for the slope.
