This is actually called a mapping diagram but the answer is C.
Because the right circle represents the x variable and the left circle is the y variable. So you just follow the arrows. -3 is pointing to 4 so that's a pair or (-3,4)
A-y=4.50x ,4.50 is the slope because for each shirt she sells that is how much she makes and she doesn't have an original value for a y-intercept.
B- 1 ,each tee-shirt she makes she will profit 4.50 for a single so she makes money after the first one.
C-129 ,because you need to find how much each tee-shirt costs in the bunch of 70 and divide it from 800 and round to 129.
