Answer:
By process of elimination, we can eliminate:
- A: y = 3x - 1
- C: y = 3x + 1
- B: y = -3x
A and C don't work because the given line has it's y-intercept at the origin, therefore, no y-intercept is written. B is not it either because the line does not go down from left to right, therefore, the slope is not negative.
The answer is D: y = 3x because since the line goes up from left to right, the slope is positive, and the y-intercept is the origin, so the equation will have no b.
