Question

What is the slope of the line through (-7,-2)(−7,−2) and (-6,7)(−6,7)? Choose 1 answer: Choose 1 answer: (Choice A) A -\dfrac19− 9 1 ​ (Choice B) B -9−9 (Choice C) C 99 (Choice D) D \dfrac19 9 1 ​

Answer 1

`\bf (\stackrel{x_1}{-7}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{7}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-(-2)}{-6-(-7)}\implies \cfrac{7+2}{-6+7}\implies \cfrac{9}{1}\implies 9`
