Example 3: Graphing Linear Functions

Step-by-step worked example for this lesson track.

Problem

If y=5x+6, find y at x=1\text{If }y=5x+6\text{, find }y\text{ at }x=1

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=6x+6,  x=−3⇒y=−12y=6x+6,\;x=-3\Rightarrow y=-12

3. Conclude

y=11y=11

Final answer

y=11y=11
