Answer: B. y = -3x
Step-by-step explanation:
By plugging in the given point into each answer choice for the x and y values for which ever equation is true that is the correct answer.
For the purpose of speeding things up the correct answer is B y = -3x
If we plug in the point give, (1, -3) for (x, y) then we get the equation:
-3 = -3 * 1
This equation when solved: -3 = -3 which is true so this is the correct answer.
