Answer:
They're not parallel, because 4x and 12x are not the same slope
The least common multiple (LCM) of 5, 6, and 7 is 210.
5 × 42 = 210
6 × 35 = 210
7 × 30 = 210
Answer:
the first image (the image with the upward sloping line)
Step-by-step explanation:
If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.
If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

well, the last part will be with a calculator, but you can simply use the area in π terms.
