So basically we want to find how much sets of 40s there are in 15.
So, just 15/40.
15/40 = 0.375 = 3/8
So if you want it in fraction form, 3/8 of a pound, and if you want it in decimal form, 0.375 of a pound.
Answer:
y= 3 + 3/4x sooooooo 3/4 is the slope... I think

A)it is not a function;
Becacuse we had an input (3) with two outputs (7) and (6); look at the points (3,7) and (3,6)
B) is a function
Because ir relates an input to one output.
C)it is not a function
Becacuse we had an input (4) with two outputs (2) and (6); look at the points (4,2) and (4,6)
