#### Answer

$m=\text{undefined}$

#### Work Step by Step

With the given points, \begin{array}{l}\require{cancel} y_1= 7.5 ,\\y_2= -3.2 ,\\x_1= 6.8 ,\text{ and }\\ x_2= 6.8 .\end{array} Using $m=\dfrac{y_1-y_2}{x_1-x_2}$ or the Slope Formula, the slope, $m,$ of the line is \begin{array}{l}\require{cancel} m=\dfrac{7.5-(-3.2)}{6.8-6.8} \\\\ m=\dfrac{7.5+3.2}{6.8-6.8} \\\\ m=\dfrac{10.7}{0} \\\\ m=\text{undefined} .\end{array}
