Exhibit 1A-2 Straight line
In Exhibit 1A-2, explain the slope of straight line CD.
A) As the X value increases by 20, the Y value increases by 5, so the slope is 4.
B) As the Y value increases by 5, the X value increases by 20, so the slope is 1/4.
C) As the X value increases by 10, the Y value increases by 5, so the slope is 2.
D) As the Y value increases by 5, the X value increases by 10, so the slope is 1/2.

B) As the Y value increases by 5, the X value increases by 20, so the slope is 1/4. 
C) As the X value increases by 10, the Y value increases by 5, so the slope is 2. 
D) As the Y value increases by 5, the X value increases by 10, so the slope is 1/2.

Quizplus · Accepted Answer

The slope of a line represents how much the Y value changes for every unit increase of the X value. In this case, as the Y value increases by 5, the X value increases by 10, so the slope is 1/2. Therefore, choice D is the correct answer.
