Slope: **Undefined**

Line:

Point-slope: N/A

Slope-intercept: N/A

Standard form:

Domain:

Range:

#### Explanation:

By looking at the points, we can tell that the line is vertical at the y-axis. To prove this, let's find the slope:

Noting can be divided by 0, so the slope is undefined. **Our equation for this line will be #x=0#.**

We can't write an equation for this line in point-slope form or in slope-intercept form because the undefined slope prevents us. Only standard form exists because it doesn't require a slope:

The only x-value that the line is at is
