Example 1: Graphing Linear Functions

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

Problem

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

1. Recognize Pattern

y=mx+by=mx+b

2. Apply Method

y=2x−1,  x=1⇒y=1y=2x-1,\;x=1\Rightarrow y=1

3. Conclude

y=5y=5

Final answer

y=5y=5
