1-9 PATTERNS, EQUATIONS,
AND GRAPHS
Objective:
Use tables, equations, and graphs to describe relationships
A.REI.10:
Understand that the graph of an equation in two variables
is the set of all its solutions plotted in the coordinate plane,
often forming a curve (which could be a line).

 Is (3, 10) a solution of the equation y = 4x?
 y=4x
 10=4(3)
 10 ≠ 12……(3,10) is not a solution of the equation
