Question 464397: Hi So this is my question, the work is already done, but my Professor wants to know this:
There is a difference between a line with no slope and a line with a slope of 0. What is that difference?

Any help is appreciated!!! thank you :)

Find the slope and the y-intercept of each line whose equation is given.
3.6 #30
y − 3 = 5
y=8
y int (0,8)
no slope, horizontal line


I'm not sure if I am right with this:
No slop the line y=8 has a slope of 0

Lines that go uphill to the right have slopes which are positive numbers.
Like these:



Lines that go downhill to the right have slopes which are negative numbers.
Like these:



Lines that are horizontal have slope 0  (zero), like these:



Lines that are vertical have NO slope, like these:



Vertical lines are the only lines with NO slope.
All other lines have slopes.

y = 8 is the equation of a horizontal line with slope = 0 
and y-intercept (0,8) and it has no x-intercept.  Like this:



x = 8 is the equation of a vertical line with NO slope 
and x-intercept (8,0) and it has no y-intercept.  Like this:
