Question 57489: Find the slope and y-intercept.
x = –7
Answer by funmath(2933)   (Show Source):
You can put this solution on YOUR website! This is a trick question. This is a special case. Any time you have x=k, where k is a real number, and there is no y you have a vertical line going through k.
Vertical lines have undefined slopes.
x=0 can BE the y-axis, but no vertical line can cross the y-axis.
:
Find the slope and y-intercept.
x = –7
Is a vertical line going through x=-7.
It has an undefined slope and no y-intercept.
Happy Calculating!!!
