Undefined slope is when a line is exactly on the y-axis, for reasons unknown, the slope of a line on the y-axis cannot be determined, so therefore it it "undefined."
A line with no slope is a line with a slope of zero. In order for a line to have a slope of zero, it must be directly on the x-axis, meaning it is horizontal. Horizontal lines are straight and have no slope

What is the difference between undefined slope and zero slope?
A line with an undefined slope is a vertical line. A line with a slope of zero is a horizontal line. If you use the formula for slope m = (y2-y1) divided by (x2-x1)... For an undefined slope you will get zero in the denominator, which you cannot have because you cannot divide by zero. For a slope equal to zero, you will get a zero in the numerator. Zero divided by any non-zero denominator, will give you a slope of zero.
What is the direction of the line with an undefined slope?
A vertical line has an undefined slope.
Is an undefined slope a vertical or horizontal line?
An undefined slope is vertical.
Write an equation for undefined slope?
The equation of a line with an undefined slope is x = a.
Slope of a vertical line?
The slope of a vertical line is undefined. Horizontal slope is 0.
