Undefined slopes are when x equals a certain number.

Slope-Intercept Form: y = mx + b

• m - slope

• b - y-intercept

Explanation:

From the given choices, B is the correct answer.

A has a slope of 0, so m = 0 and would become a horizontal line.

C has a negative slope, so it is not undefined.

D has a positive slope, so it is not undefined.

B shows a vertical line, and so it has an undefined slope.
