UNIT 3 LESSON 2
LINEAR EQUATIONS
Do Now: Copy the objectives
•  I will be able to identify and classify linear
equations with at least 75 % accuracy by
the end of class.
•  I will be able to analyze equations inorder
to explain in detail the number of solutions
a specific type of equation has with at
least 75 % accuracy by the end of class.
•  I will be a ble to graph linear equations in
two variables and systems of equations
and use the graphs to find the solutions
with at least 75 % accuracy by the end of
class.
EQUATIONS AND EXPRESSIONS
¡ D escribe and discuss the expression and
equations shown .
§  Tell me if these are expressions, equations, are they functions, are
they linear.
LINEAR EQUATION
¡ H ow many variables does the equation
3 = 2x – 6 have?
¡ W hat is the solution to 3 = 2x – 6 ?
SOLVE LINEAR EQUATIONS
¡ H ow many variables does the equation
y + 3 = 2x – 6 have?
¡ D escribe the solution set of y + 3 = 2x – 6.
¡ I n your notebook, create a graph of
y + 3 = 2x – 6.
GRAPH A SYSTEM OF EQUATIONS
¡  On the same coordinate plane, graph y + 3 = 2x – 6 and
y = -x. A set of two or more equations with the same variables
is a system of equations.
¡  Describe the solution set of the system y = -x and
y + 3 = 2x – 6
