I really don't understand this topic and really hope no one asks about it.
I wouldn't mind a question or two on this topic.
Every question on the exam should be on this topic.
Finding the slope of a line
Parallel and perpendicular lines
Finding the equation of a line given points
Finding the equation of a line given a point and some other information
Interpreting the slope and intercept of the equation of a line.
Determining whether something is a function
Finding the domain and range of a function
