Dwayne will multiply the amount of each ingredient of a brownie recipe by 4 to make brownies for a bake sale at school. if the recipe calls for 1/3 cup of oil to make all the brownies?

Divide the total mount needed by 4 :

1/3 / 4 = 1/3 / 4/1 = 1/3 x 1/4 = 1/12 cup for the original recipe

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
