Question

34. A horizontal line passes through the point (2,3).
What is the slope of the line?

Answer 1

Answer is F

A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.
