Answer:
I'm sorry is there a chart/graph, etc. to give us more information?
Without the added information there is no way for me to answer.
If you repost this question with a picture I would be more than happy to help.
Answer:

Step-by-step explanation:
we are asked to evaluate
÷
Above we are given mixed fraction which can be converted in proper fraction using formula given below
Hence


Also


Hence
÷ 
can be written as
÷ 
Also we know the rule for dividing fraction is as given below
÷
= 
Hence
÷
= 
=

Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
