Well... you need to find your slope first for starters. In order to find you slope it would be y2-y1/x2-x1... rise/run. So that would make your slope 6/3 and you can simplify that to 2/1 because divide it by 3. In order to find your y-intercept, you need to have (x) at 0 and wherever (y) is on that line, it would be your y-intercept.
Answer:
x=0
Step-by-step explanation:
"y varies directly as x," means that when one increases/decreases, the other does the same thing
so when y decreses by 4 from 16 to 12, x decreases by 4 too
4-4=0
