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
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
