The amount of oxygen in the reactants is 4 atoms. in the products, the oxygen is distributed to water (h2o) and o2 gas. which coefficients would be placed in front of water and oxygen? a. 2 in front of water and 2 in front of oxygen b. 1 in front of water and 2 in front of oxygen c. 1 in front of water and 1 in front of oxygen d. 2 in front of water and 1 in front of oxygen

D. 2 in front of water and 1 in front of oxygen

Just took the test the answer is D and he/she is right (:

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
