\bf \begin{array}{lllll} &x_1&y_1\\ % (a,b) &({{ -1}}\quad ,&{{ -5}})\quad \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies 0 \\\\\\ % point-slope intercept y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-(-5)=0(x-(-1))\\ \left. \qquad \right. \uparrow\\ \textit{point-slope form} \\\\\\ y+5=0(x+1)\implies y+5=0\implies \boxed{y=-5}

y = mx + b
where
m = slope
b = y-intercept

y = 0x - 5
