    now to fine the equation grab that slope and uset it in the point-slope form \(\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({\color{red}{ 3}}\quad ,&{\color{blue}{ 1}})\quad % (c,d) &({\color{red}{ 7}}\quad ,&{\color{blue}{ -1}}) \end{array} \\\quad \\ % slope = m slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ -1}}-{\color{blue}{ 1}}}{{\color{red}{ 7}}-{\color{red}{ 3}}}\implies \cfrac{-\cancel{2}}{\cancel{4}}\implies -\cfrac{1}{2} \\ \quad \\ % point-slope intercept y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values}\\ \qquad \uparrow\\ \textit{point-slope form}\)

    so y-y1=-1/2(x-x1)

    or \(\bf y-{\color{blue}{ 1}}={\color{green}{ -\cfrac{1}{2}}}(x-{\color{red}{ 3}})\qquad \textit{plug in the values}\\ \qquad \uparrow\\ \textit{point-slope form}\)
