Answer 1

x=2

Answer 2

thankz

Answer 3

.... sigh

Answer 4

what does it mean when he says x=2?

Answer 5

lol idnk but its undefined

Answer 6

:) undefined is right; x=2 is the equation for the line. The line itself exists, a numerically defined slope for it does not.

Answer 7

slope is the measure of how far y moves while x moves; in this case, x never moves and y is always moving;

Answer 8

so the slope is not defined :)
