OpenStudy (jdoe0001):

can you tell the coordinates of those 2 points on the line?

OpenStudy (anonymous):

-3,3 and 1,-5

OpenStudy (jdoe0001):

yeap so \(\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ &({\color{red}{ -3}}\quad ,&{\color{blue}{ 3}})\quad &({\color{red}{ 1}}\quad ,&{\color{blue}{ -5}}) \end{array} \\\quad \\ slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

OpenStudy (anonymous):

Yeah, so the slope is -8/4, so your slope =-2

OpenStudy (jdoe0001):

Yeah, so the slope is -8/4, so your slope =-2 \(\huge \checkmark\)
