Write a rule for the linear function in the table

The answer is D. To figure this out, all you need to do is plug in the x's. 

A isn't correct because f(1) = 4(1), however, the chart says it equals 3.

B isn't correct because f(1) = 1 - 4, however, the chart says it should be 3 (not negative 3)

C isn't correct because f(1) = 1 + 4, but the graph says it's supposed to be 3, not 5.

That leaves D, but it's always great to double check. f(1) = 4 - 1. 3=3. Therefore, D is correct.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
