YES
How do you identify a linear equation from a proportional equation on a ...
graph
equation
table
If it's proportional it starts at 0 and linear can start anywhere
In a linear there might be a b or might not in the equation y=mx+b while on a proportional their is no b
For a linear any sequence will do but for a proportional their has to be a relationship with one side and another
What is the sum of the exterior angles?
360 degrees

ex. +,+ =+ (this cannot be used now)
+,-=-
-,-=+
