Question

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

Answer 1

x=1/2, so in this equation the slope is undefined.

Answer 2

Answer:

undefined

Step-by-step explanation:

Equation of a line is y=mx+b

where m is the slope and b is the y intercept

$2x-1=0$

Here there is no y term, so we solve for x

$2x-1=0$

Add 1 on both sides

$2x=1$

Divide both sides by 2

$x=\frac{1}{2}$

If we have equation of the for x= some number then it is the equation of the vertical line. the slope of vertical line is undefined.

Slope of $2x-1=0$ is undefined
