Example 11: Graphing Linear Functions

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

Problem

If y=1x+3, find y at x=3\text{If }y=1x+3\text{, find }y\text{ at }x=3

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=1x−7,  x=6⇒y=−1y=1x-7,\;x=6\Rightarrow y=-1

3. Conclude

y=6y=6

Final answer

y=6y=6
