Answer:

Step-by-step explanation:

I'll get you the answer. You pick it from what you are given.

The slope of the perpendicular is m1 * m2 = - 1

m1 = 3

m2 = -1 / m1

m2 = -1 / 3

So far what you have is

y = (-1/3) x + b

Use the point go get b

x = -1

y = - 3

y = (-1/3) *x + b

-3 = (-1/3)*-1 + b

-3 = 1/3 + b  

-3 - 1/3 = b

b = -3.33333  or

b = -3 1/3

b = -10/3              

So the answer is

y = (- 1/3) x - 10/3            or

y = (-1 / 3)x - 3.3333       or

y = (-1/3 )x  - (3 1/3)
