How do you find slope, point slope, slope intercept, standard form, domain and range of a line for Line A (0,-7) (0,-12)?

Slope: Undefined
Line: x=0
Point-slope: N/A
Slope-intercept: N/A
Standard form: x+0y=0
Domain: (0)
Range: (-oo,oo)

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:

(-12-(-7))/0-0=-5/0

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:

x+0y=0

The only x-value that the line is at is 0, so the domain is (0). The line extends for infinity in both directions, so the range is (-oo,oo).
