Answer:

(a) 24 cents.

(b) The slope is:
24

Explanation:

(a) Notice that the x-axis is labeled as "Weight (ounces)" and the y-axis is labeled as "Cost (cents)".

You can identify that when:


x=1;y=24


x=2;y=48


x=3;y=72

Then, you can determine that the cost of the cheese increases 24 cents for each ounce Dale buys.

(b) The slope can be found with the following formula:


m=(y_2-y_1)/(x_2-x_1)

If you choose two points on the line, for example the points (0,0) and (2,48), and you substitute the corresponding coordinates into the formula, you get that the slope of the line is:


m=(0-48)/(0-2)\\\\m=24
