# Day 4: Graphing Linear Functions

```Day 4: Graphing Linear Functions
Goal: To solve for a variable AND To graph linear functions
using tables or equations
Standard: 9.2.1.8 – Make Qualitative statements about the rate of
change of a function based on its graph or table of values
9.2.2.3 – Sketch graphs of linear, quadratic and exponential
functions and translate between graphs, tables and symbolic
representations. Know how to use graphing technology to graph
these functions.
Guiding Question: What and how are the many ways I can
graph a line?
Materials: Pencil, Folder, Student Packet
