through (8,3) perpendicular line y-17=5(x-13)

Question

need help with this kinda hard but its ok

Answer 1

You have the point slope form of the equation of a line whose slope is 5. The slope of the perpendicular line is -1/5. In point slope form, the equation of the perpendicular line passing through (8,3) is

y - 3 = (-1/5)(x - 8)
