Example 5: Graphing Linear Functions

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

Problem

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

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=5x−5,  x=−4⇒y=−25y=5x-5,\;x=-4\Rightarrow y=-25

3. Conclude

y=−5y=-5

Final answer

y=−5y=-5
