Answer Key 3.3

$m=-\dfrac{3}{5}$
$m=\dfrac{5}{4}$
$m=-4$
$m=\dfrac{2}{7}$
$m=-\dfrac{1}{3}$
$m=\dfrac{3}{5}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{15-10}{-2-2}\Rightarrow \dfrac{-5}{4}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-12-2}{-6-1}\Rightarrow \dfrac{-14}{-7}\Rightarrow 2$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-10}{0--5}\Rightarrow \dfrac{-10}{5}\Rightarrow -2$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{8--2}{7-2}\Rightarrow \dfrac{10}{5}\Rightarrow 2$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-10-6}{-8-4}\Rightarrow \dfrac{-16}{-12}\Rightarrow \dfrac{4}{3}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-6-6}{9--3}\Rightarrow \dfrac{-12}{12}\Rightarrow -1$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-4--4}{10--2}\Rightarrow \dfrac{0}{12}\Rightarrow 0$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-5}{2-3}\Rightarrow \dfrac{-5}{-1}\Rightarrow 5$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{8-4}{-6--4}\Rightarrow \dfrac{4}{-2}\Rightarrow -2$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-7--6}{-7-9}\Rightarrow \dfrac{-1}{-16}\Rightarrow \dfrac{1}{16}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{4--9}{6-2}\Rightarrow \dfrac{13}{4}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-2}{5--6}\Rightarrow \dfrac{-2}{11}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{0-0}{-5--5}\Rightarrow \dfrac{0}{0} \therefore \text{Undefined}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-13-11}{-3-8}\Rightarrow \dfrac{-24}{-11} \Rightarrow \dfrac{24}{11}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-7-9}{1--7}\Rightarrow \dfrac{-16}{8} \Rightarrow -2$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{7--2}{1-1}\Rightarrow \dfrac{9}{0} \therefore \text{Undefined}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-9--4}{-8-7}\Rightarrow \dfrac{-5}{-15} \Rightarrow \dfrac{1}{3}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{-3--5}{4--8}\Rightarrow \dfrac{2}{12} \Rightarrow \dfrac{1}{6}$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{4-7}{-8--5}\Rightarrow \dfrac{-3}{-3} \Rightarrow 1$
$m=\dfrac{\Delta y}{\Delta x}\Rightarrow \dfrac{1-5}{5-9}\Rightarrow \dfrac{-4}{-4} \Rightarrow 1$
