Grade Level/ Course: 8th Grade
Standard with
code:
8.F.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=s 2 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.
Domain:
