If you can either use rise over run to dtermine the slope or use the point slope formula. For example, take the two points (0,1) and (1,2) using the point slope formula, you'll get 1 in the end.
Slope is determined by rise over run. Meaning that the number of units the slope goes up/down divided by the number of units the slope goes to the left/right is the slope. The rise is one, and the run is one. 1 over 1 equals 1.
