Answer:
5 and 1/3 cups of water.
Step-by-step explanation:
Set up a proportion like this:
2:3 for the original recipe
Then a second proportion for the recipe Jacoby used:
w:8 (use w for the unknown water amount)
Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

Use cross multiplication to get the new equation:
8 x 2 (or 16) = 3w
Then, divide both sides by 3 to get the amount for w, or water, by itself:
5 and 1/3 = w
I hope this helps! ☺
Get this equation into y=mx+b form.
y-2=-3(x-4)
y-2=-3x+12
y=-3x+12+2
y=-3x+14
Hope this helps!
And just a note, this is provided in point-slope formula, meaning there is a point on the line, (4,2), based on the initial equation.
