Question: How do I graph $\frac{1}{2}x-1$, $x \ne 4$
1. **State the problem:** We want to graph the function $$y=\frac{1}{2}x-1$$ with the restriction that $$x \ne 4$$.
2. **Understand the function:** This is a linear function with slope $$\frac{1}{2}$$ and y-intercept $$-1$$.
3. **Plot the line:**
- Start by plotting the y-intercept at point $$(0,-1)$$.
- Use the slope $$\frac{1}{2}$$ which means rise 1 unit up for every 2 units right.
- Plot another point at $$(2,0)$$.
- Draw a straight line through these points.
4. **Apply the restriction $$x \ne 4$$:**
- At $$x=4$$, calculate $$y=\frac{1}{2}(4)-1=2-1=1$$.
- Mark a hollow circle at $$(4,1)$$ to indicate the point is not included.
5. **Summary:** The graph is a straight line with slope $$\frac{1}{2}$$ and y-intercept $$-1$$, but with a hole at $$(4,1)$$ because $$x$$ cannot be 4.
