Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other. Wikipedia
1. 1/4, 2/7, 3/8
2. 12/5
3. 3/4, 7/10, 7/12
4. 1/6, 1/2, 1/4
I'd use the point-slope form, because it'd require the least amount of work.
The slope of this line is 3/1, or just 3.
Thus, y = mx + b becomes 3 = 3(1) + b, and b = 0. Thus, we get y = 3x (ans.)
