1. What is the slope of the line graphed below?
Coordinate 1:
Coordinate 2:
Slope:

I can't see the line but if you start at a point where the line crosses over an intersecting corner and find the next nearest corner where it intersects the slope will be however many up(or down - if its down its negative) you have to go/ how many sideways you have to go

ex:

so in example A the slope would be 2/1 which simplifies to 2 and in example B the slope would be -3/2
