Question

Help ;*
Line AB contains points A (−3, 5) and B (−3, 3). Line AB has a slope that is
Zero, Undefined, Positive, or Negative

Answer 1

notice the x coordinate value is the same for both of those different points

Answer 2

Yea!!

Answer 3

if you graphed it, what does it look like connecting those >?

Answer 4

negative

Answer 5

same x coordinate, but different y coordinates form a vertical line like that

Answer 6

its negative and positive so is it undefined ?

Answer 7

since slope is change in y divided by change in x you get
\[\frac{ y~change }{ x~change }=\frac{ 3 - 5 }{ -3-(-3) }\]

Answer 8

you end up with a number divided by zero
-2/0 you cant divide by a zero, it is UNDefined,
vertical lines have an undefined slope

Answer 9

vertical line - undefined slope (number/0)
horizontal line - zero slope (0/number)

Answer 10

thanks uuu ;*

Answer 11

yay now i get it.
