Question

What is the slope of the line that passes through the points (-3, -2) and (6, 8)?

A

B

C

D

Answer

The correct answer is B. Using the formula for slope, you should have:

Special Slope Cases

Horizontal lines have a slope of zero (m = 0). Since this makes the "mx" term of the linear equation
disappear, all horizontal lines are an equation of the form y = b.

Vertical lines have an undefined slope. The "run" on a vertical line would be zero, and when you divide
by zero, you get an undefined answer. Vertical lines are equations in the form of x = n, where n is the x-
intercept of the graph.
