Answer:
3x+4 is the closest.
Explanation:
The '-' symbol for C and D causes the line to face the wrong way - so these are not an option.
The 1/3 in B means the line is 3x as shallow and also is not it.
3x+4 is steep and has the same general line in the same quadrant.
(Also, photomath is a great tool to visualize this as well)
