Answer Key 3.3

  1. [latex]m=-\dfrac{3}{5}[/latex]
  2. [latex]m=\dfrac{5}{4}[/latex]
  3. [latex]m=-4[/latex]
  4. [latex]m=\dfrac{2}{7}[/latex]
  5. [latex]m=-\dfrac{1}{3}[/latex]
  6. [latex]m=\dfrac{3}{5}[/latex]
  7. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{15-10}{-2-2}\Rightarrow \dfrac{-5}{4}[/latex]
  8. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-12-2}{-6-1}\Rightarrow \dfrac{-14}{-7}\Rightarrow 2[/latex]
  9. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-10}{0--5}\Rightarrow \dfrac{-10}{5}\Rightarrow -2[/latex]
  10. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{8--2}{7-2}\Rightarrow \dfrac{10}{5}\Rightarrow 2[/latex]
  11. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-10-6}{-8-4}\Rightarrow \dfrac{-16}{-12}\Rightarrow \dfrac{4}{3}[/latex]
  12. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-6-6}{9--3}\Rightarrow \dfrac{-12}{12}\Rightarrow -1[/latex]
  13. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-4--4}{10--2}\Rightarrow \dfrac{0}{12}\Rightarrow 0[/latex]
  14. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-5}{2-3}\Rightarrow \dfrac{-5}{-1}\Rightarrow 5[/latex]
  15. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{8-4}{-6--4}\Rightarrow \dfrac{4}{-2}\Rightarrow -2[/latex]
  16. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-7--6}{-7-9}\Rightarrow \dfrac{-1}{-16}\Rightarrow \dfrac{1}{16}[/latex]
  17. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{4--9}{6-2}\Rightarrow \dfrac{13}{4}[/latex]
  18. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-2}{5--6}\Rightarrow \dfrac{-2}{11}[/latex]
  19. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-0}{-5--5}\Rightarrow \dfrac{0}{0} \therefore \text{Undefined}[/latex]
  20. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-13-11}{-3-8}\Rightarrow \dfrac{-24}{-11} \Rightarrow \dfrac{24}{11}[/latex]
  21. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-7-9}{1--7}\Rightarrow \dfrac{-16}{8} \Rightarrow -2[/latex]
  22. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{7--2}{1-1}\Rightarrow \dfrac{9}{0} \therefore \text{Undefined}[/latex]
  23. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-9--4}{-8-7}\Rightarrow \dfrac{-5}{-15} \Rightarrow \dfrac{1}{3}[/latex]
  24. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-3--5}{4--8}\Rightarrow \dfrac{2}{12} \Rightarrow \dfrac{1}{6}[/latex]
  25. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{4-7}{-8--5}\Rightarrow \dfrac{-3}{-3} \Rightarrow 1[/latex]
  26. [latex]m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{1-5}{5-9}\Rightarrow \dfrac{-4}{-4} \Rightarrow 1[/latex]
