[tex](x_1,y_1) = (-10,-7),~~(x_2, y_2) =(-5,-9)\\\\\text{Slope,}~ m =\dfrac{y_2 -y_1}{x_2 - x_1} =\dfrac{-9+7}{-5+10} = -\dfrac{2}{5} \\\\\\\text{Equation of line:}\\y -y_1 = m(x-x_1)\\\\\implies y +7 = -\dfrac{2}5 \left(x+10 \right)\\\\\implies 5y+35 = -2x -20\\\\\implies 5y+2x +35 +20 =0\\\\\implies 2x +5y +55=0[/tex]
