The slope of the line whose equation is 2x - 1 = 0 is
a. 0 b. 1/2 c. no slope

2 is your slope

Step-by-step explanation:

Note that the equation is: y = mx + b

b is your y-intercept = -1

m is your slope = 2

x & y = (x , y) = you're point.

So if there is option that has 2 for your answer, it should be that one.

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
