```Unit 6 Lesson 2: Graphing Quadratics/Linear Functions (Domain/Range/Shifts)
Linear Equations
• To graph a linear equation put in slope intercept form: y = mx + b or f(x) = mx + b
• “m” represents the ______________ = ______________
• “b” represents the __________________
• You can graph a linear equation by starting with the y-intercept. From this point use your
slope to find the next point.
• If your slope is ___________________: ______________________
• If you slope is ____________________: ______________________
Example 2) Graph 𝑓(𝑥) = −1/2𝑥 + 4
Example 1) Graph 𝑦 = 5𝑥 − 3

 Vertex Form:
• In standard form “C” is the __________________ (0, C)
• The _____________________of the _____________________and the
___________________________ can be found using x =
•
•
After you find the x-value of the vertex, plug in the ___________________ to find the
____________________
You can find the x-intercepts on the _____________________, ___________________, or using
the __________________________________________!
