Answer:
-4
Step-by-step explanation:
The form of a liner equation is y=mx+b. b is 0 in this example. So we are left with y=-4x
-4 is the m, the slope. It is also called the unit rate of change. It tells us how much y changes for each 1x unit.
y x
0 0
-4 1 One unit changes y by -4 : The unit rate of change.
-8 2
4.66
37.28$ / (divided by) 8 = 4.66
If y=mx+b,
You can't differentiate a constant, so dy/dx=m.
118 ounces because 1 pound equals 16 ounces
