Example 6: Graphing Linear Functions

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

Problem

If y=4x+6, find y at x=6\text{If }y=4x+6\text{, find }y\text{ at }x=6

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=−1x−9,  x=1⇒y=−10y=-1x-9,\;x=1\Rightarrow y=-10

3. Conclude

y=30y=30

Final answer

y=30y=30
