1-38.

Consider the equation $y=\frac{1}{2}x-4$.

1. Without graphing, where is 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. On graph paper, make a table and graph $y=\frac{1}{2}x-4$.

3. Using your graph from part (b), how can you find the $x$-intercept of $y=\frac{1}{2}x-4$? How do you find it in the table? Explain.

Find the point where $y=0$.
