$color(indigo)("Equation of the line is "color(crimson)(21x + 10y + 59 = 0$

Equation of the line passing through two points is given by

$(y-y_1) / (y_2 - y_1) = (x - x_1) / (x_2 - x_1)$

$(x_1,y_1) = (1,-8), (x_2,y_2) = (-9,13)$

$:. (y + 8) / (13+8) = (x - 1) / (-9-1)$

$(y + 8) / 21 = (x - 1) / -10$

$-10y - 80 = 21x - 21$

$color(indigo)("Equation of the line is "21x + 10y = -59$

What is the equation of the line passing through (1,-8)(1,-8) and (-9,13)(-9,13)?
