First, you have to find the y-intercept. In this case, the y-intercept is -3. I know this because it is in the formula. Once you know that, then you could start graphing the line. You would start at -3, then go up 5 units. If the 5 was negative, you would go down 5 units. When you get to the location, you move 1 unit to the right. That's how you graph a line based on the equation. It's not that difficult to understand once you know the formula.
