A line L with a slope of 1/4 passes through the points (0,1/2) and (4,y). What is the value of y? This is an SAT prep question, and the answer is supposed to be 3/2 (1.5), but there's no explanation as to how the problem was solved.

slope means for 4 x units, one y advance. You have 4 xunits (4-0), so y goes up 1 to 1.5.
