B) 12 
C) 18 
D) Infinite

Quizplus · Accepted Answer

The slope of a line is calculated by Δy/Δx, where Δy is the change in y (vertical) and Δx is the change in x (horizontal). For line (2), there is no change in the y-coordinate as it is a horizontal line. Therefore, the change in y (Δy) is 0. Any number divided by 0 is undefined, but in this case, the slope of line (2) is 0. Hence, the correct answer is A) 0.
