Example 8: Graphing Linear Functions

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

Problem

If y=4x−1, find y at x=6\text{If }y=4x-1\text{, find }y\text{ at }x=6

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=−5x−3,  x=−2⇒y=7y=-5x-3,\;x=-2\Rightarrow y=7

3. Conclude

y=23y=23

Final answer

y=23y=23
