Answer:
Step-by-step explanation:
To be perpendicular the product of the two slopes is equal to negative one.
m1(m2)=-1, in this case the slope of the reference line is 1/3 so the other line will have a slope
m/3=-1
m=-3 so our perpendicular line is
y=-3x+b, using point (3,-5) we can solve for the y intercept b
-5=-3(3)+b
-5=-9+b
b=4 so the completed perpendicular line passing through point (3,-5) is
y=-3x+4
