Linear Equations and Functions
Linear equations are called "linear" because they make a "blank" line when we graph them.
straight

What is the difference between two shapes that are congruent and two that are similar?
Corresponding parts of congruent shapes are equal vs. corresponding parts of similar shapes are in a fixed ratio with each other.
Slope is "blank"/"blank"
