Madeline needs to find the slope of the line that passes through the points (9, 12) and (7, 4). She sets up the following work:
12-4/7-9
Has she set up her work correctly? Why or why not?
She has everything correct but one thing. In order to have her answer correct, she must put the 9 in front of the 7 because the bigger number needs to go in front.
