Answer:

y = ½x

_____

k = ½

Explanation:

[# of donuts] 2 → [total price] $1

[# of donuts] 12 → [total price] $6

[# of donuts] 3 → [total price] $1.50

[# of donuts] 7 → [total price] $3.50

Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.

Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.
