1. x-intercept is [latex]\left(4,0\right)[/latex]; y-intercept is [latex]\left(0,3\right)[/latex]. 2. [latex]\left(-5,\frac{5}{2}\right)[/latex]Solutions to Odd-Numbered Exercises
1. Answers may vary. Yes. It is possible for a point to be on the x-axis or on the y-axis and therefore is considered to NOT be in one of the quadrants. 3. The y-intercept is the point where the graph crosses the y-axis. 5. The x-intercept is [latex]\left(2,0\right)[/latex] and the y-intercept is [latex]\left(0,6\right)[/latex]. 7. The x-intercept is [latex]\left(2,0\right)[/latex] and the y-intercept is [latex]\left(0,-3\right)[/latex]. 9. The x-intercept is [latex]\left(3,0\right)[/latex] and the y-intercept is [latex]\left(0,\frac{9}{8}\right)[/latex]. 11. [latex]y=4 - 2x[/latex] 13. [latex]y=\frac{5 - 2x}{3}[/latex] 15. [latex]y=2x-\frac{4}{5}[/latex] 17. [latex]d=\sqrt{74}[/latex] 19. [latex]d=\sqrt{36}=6[/latex] 21. [latex]d\approx 62.97[/latex] 23. [latex]\left(3,\frac{-3}{2}\right)[/latex] 25.
