[tex]\bf \begin{array}{ccccccccc} &&x_1&&y_1\\ % (a,b) &J&(~{{ 4}} &,&{{ -4}}~) \end{array} \\\\\\ % slope = m slope = {{ m}}\implies 4 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-4)=4(x-4)\implies y+4=4x-16 \\\\\\ y=4x-16-4\implies y=4x-20[/tex]
