Question

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 area of land mowed 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 1

The slope of the line through these two points is 0.5, which means that for each hour moving a lawn, 0.5 more lands of area are mowed.

Explanation:

Slope of a line:

Suppose we have two points in a line. The slope is the change in y divided by the change in x. It states how much y changes when x changes by 1.

In this question:

x: Time in hours to move a lawn.

y: Area of land.

Two of his points are (3, 1.5) and (5, 2.5).

Change in y: 2.5 - 1.5 = 1

Change in x: 5 - 3 = 2

Slope: 1/2 = 0.5

The slope of the line through these two points is 0.5, which means that for each hour moving a lawn, 0.5 more lands of area are mowed.
