Fat grams a cup of milk contains 7.5 grams of fat. (a) give a formula for that calculates the number of fat grams in x cups of milk. (b) what is the slope of the graph of f(x) ? (c) interpret the slope as a rate of change.

This is the concept of algebra, given that Fat Grams A cup contains 7.5 g of fat, the formula for fat in x cups will be given by:
Total amount of fat=(number of cups)*(amount of grams per cup)
Let total amount be y;
number of cups=x
thus;
y=7.5*x
y=7.5x

Since the equation of the straight line is given by y=mx+c, where m-slope.
The slope of our equation will be m=7.5
