The formula for the slope of a line is y=mx+b. Min that formula is equal to the slope of the line, and b is equal to the point on the y axis where the line crosses it, or the y intercept. You start out finding the y intercept, which on this formula is -2, or two units below the origin on the y axis. Then you find the slope. The slope of a line is equal to the rise over the run (rise/run). The rise of a line is how many units it goes up, and the run is how many units it travels right. On this line, the rise is 3 units, and the run is 1 unit. That means for every one unit it travels right, it goes up three units. So the graph of that function will look like this.
