Question

Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points​ rises, falls, is​ horizontal, or is vertical. left parenthesis 7 comma 7 right parenthesis(7,7) and left parenthesis 7 comma negative 6 right parenthesis(7,−6)

Answer 1

(7,7)(7,-6)......little tip...notice that both ur x's are the same...they are both 7. This tells me that the line is a vertical line and has an undefined slope.

if the y's would have been the same, it would have been a horizontal line with a slope of 0.
