A consensus can mean two things.
It could be a general agreement of a group, or it could be a majority of opinion.

I found two using a little C# program:
9,10,11,12,13,14,15,16
and
18,19,20,21,22
(if you're interested in the program drop me a msg)
We can use this equation to find how many questions there were on the test:
.75x = 18
This equation means 75% of what is 18.
.75x = 18
Divide both sides by .75
x = 24
There were 24 questions on the test.
Slope is the change in y over the change in x.
Using the red dots:
Slope = (4 -1)/(4- -1) = 3/5
Slope = 3/5
