you find two points where the line crosses directly on a point, (2,2) and (5,3)
and count how many spaces upwards and how spaces to the right. slope is rise/run meaning the spaces upward is the numerator and the spaces right is the run. (if you have to count downward then that's a negative number, and if you have to count left, it's negative) but, this graph has a rise of 3 and a run of 1 or 3/1 or simplified to 3
