#### A. Writing Equations from Slope and Intercepts
**In Problems 21–24, write an equation of the line with the indicated slope and y-intercept.**
21. **Slope** = 2
**y-intercept** = 1
22. **Slope** = 1
**y-intercept** = 5
23. **Slope** = \(-\frac{1}{3}\)
**y-intercept** = 6
24. **Slope** = \(\frac{6}{7}\)
**y-intercept** = \(-\frac{9}{2}\)
#### B. Using Graphs to Determine Equation Components
**In Problems 25–28, use the graph of each line to find the x-intercept, y-intercept, and slope. Write the slope-intercept form of the equation of the line.**
