This is a horizontal line example with the point is (0,5), equation is y=5.

Horizontals line always have the zero slop, as there is nothing on the x line. Then 0 divided by any numbers Is equal 0. It can be seen as all the point on a graph on y-intercept has the same value.
This is a fraction.
Domain: all real numbers
Range: y=5

This is a vertical line example with the point is (-3,0), equation is x=-3.

Vertical line always Is undefined. As no number can be divided by zero, so is undefined. It can be seen as all the point on a graph on x-intercept has the same value.
This is not a fraction.
Domain: x=-3
Range: all real numbers
