Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a lawn, and y, the size of the lawn in acres. Two of his points are (3, 1.5) and (5, 2.5). Which statement describes the slope of the line through these two points?

Answer :

slope = (y2 - y1) / (x2 - x1)
(3,1.5)...x1 = 3 and y1 = 1.5
(5,2.5)...x2 = 5 and y2 = 2.5
now we sub
slope = (2.5 - 1.5) / (5 - 3) = 1 / 2 <==
