determine whether y varies directly with x. if so, find the constant of variation k and write the equation.

x y
7 11
8 13
9 15
10 17

Not a direct variation

Step-by-step explanation:

The formula for direct variation is

y =kx

Rewriting

y/x =k

Substituting points in

11/7 =k =1.571428

13/8 =k =1.625

Since the values of k are not equal, this is not a direct variation

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.
