Grace is making lemonade. The directions say to mix 7 cups of water with 3 scoops of powdered lemonade mix. How many cups of water should she use with 6 scoops of fruit mix?

You need 14 cups of water for 6 scoops of drink mix  since it is simply double the amount of scoops

Step-by-step explanation:

(1) 7 cups water/ 3 scoops mix=7/3

(2) x cups water/6 scoops mix=x/6

(3) 7/3=x/6

(4) 42/3=x

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
