- CCSS.Math.Content.HSA-CED.A.2 Create equations in two or more variables to represent
relationships between quantities; graph equations on coordinate axes with labels and scales.
- CCSS.Math.Content.8.F.A.3 Interpret the equation y = mx + b as defining a linear function,
whose graph is a straight line; give examples of functions that are not linear. For example, the
function A = s2 giving the area of a square as a function of its side length is not linear because
its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
