Remember that slope is rise over run. Let's say that you have your slope as 2.5. This means that for every 2.5 units you go up, you go to the right 1 unit.

In fraction form, this #5/2#. This means that every 5 units you go up, you go to the right by 2 units. This is equivalent to the decimal form because if you go up 2.5 twice (this is 5 units), you go to the right 1 unit twice (this is 2 units). When possible, change from decimal to fraction notation. You can more easily/visually graph your line that way. When you change to fraction notation, your rise is your numerator. Your run is your denominator. When you have a negative slope, remember that you go to the left when you go up.

There are a few ways to graph your equation. The first way is find your y- and x-intercepts and draw a line between those two points. The second way is plot random points. The third way is to start at the y-intercept and use the slope to find the next point in your graph.
