if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
If the original slope is 0, then the opposite reciprocal of 0 is still 0. Oops! Reciprocal of 0 (n/0) is undefined! A vertical line has undefined slope, the horizontal line has slope of 0.
The slope is undefined.
No slope is undefined i.e. a vertical line slope of 0 is a horizontal line... i believe...
Points: (-1, -1) and (0, 0) Slope: 1
Slope=0 Y-intercept=0
A horizontal line has a slope of 0. If you're using the slope formula, then when the numerator is equal to 0 then the slope is 0.
If the original slope is 0, then the opposite reciprocal of 0 is still 0. Oops! Reciprocal of 0 (n/0) is undefined! A vertical line has undefined slope, the horizontal line has slope of 0.
The slope is undefined.

y=mx has a slope of m, if the slope is 0, m must be 0. So the coefficient of x is 0.
Points: (-1, -1) and (0, 0) Slope: 1
Slope = (8 - 0)/(0 - 4) = -2
if the slope is 0, the line is horizontal.
Slope=0 Y-intercept=0
Slope = 0
No, they are perpendicular.
Because V in is the slope and when A is 0 slope is not 0 so v cant be 0
