Answer:
B
Step-by-step explanation:
To find the answer, we can use the point-slope form:
Where (x₁, y₁) is a point and m is our slope.
Let's let our point (4, 1/3) be (x₁, y₁) respectively.
We also know that our slope is 3/4. So, substitute 3/4 for m.
This yields:
The choice that represents this is B.
So, our correct answer is B.
And we're done!
