Help ;* Line AB contains points A (−3, 5) and B (−3, 3). Line AB has a slope that is Zero, Undefined, Positive, or Negative
notice the x coordinate value is the same for both of those different points
Yea!!
if you graphed it, what does it look like connecting those >?
negative
|dw:1452013952595:dw|
same x coordinate, but different y coordinates form a vertical line like that
its negative and positive so is it undefined ?
since slope is change in y divided by change in x you get \[\frac{ y~change }{ x~change }=\frac{ 3 - 5 }{ -3-(-3) }\]
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
vertical line - undefined slope (number/0) horizontal line - zero slope (0/number)
thanks uuu ;*
yay now i get it.
welcome, gl
@DanJS whats that mean
you are welcome, goodluck
oh yeah
