3-41.

Consider the rule $y=\frac{1}{2}x−4$. 3-41 HW eTool (Desmos). Homework Help ✎

1. Without graphing, find the $x$-intercept of $y=\frac{1}{2}x−4$.

Set the equation equal to zero, since your output would be zero, and then solve for $x$.

2. Make a table and graph $y=\frac{1}{2}x−4$ graph paper.

3. How could you find the $x$-intercept of $y=\frac{1}{2}x−4$ with your graph from part (b)? How would you find it with the table? Explain.

• Find the point where $y=0$.
