The slope of the line whose equation is 2x - 1 = 0 is

A. 0 B. 1/2 C. no slope

C. no slope

Step-by-step explanation:

2x-1 = 0

Add 1 to each side

2x - 1+1 = 1

2x = 1

Divide by 2

2x/2 = 1/2

x = 1/2

This is a constant

The line is a vertical line. Vertical line have a slope that is undefined. Given your options, I would go with no slope
