We can use the point-slope equation:
m, the slope, is 3/4:
To find b, we plug in the point (4,1/3):
Therefore, the point-slope equation is
Now we have to see which answer matches.
Since this is not the same, we try the next one.
This is the same, so this is the answer. We should still double-check the other answers.
This one is not equivalent.
This one also does not work.
