Hope this helps!
First identify the y-int. The y-int is the b in y=mx+b. So in this case, y=2/3x-3, meaning the y intercept is -3. Now, transfer the equations on the bottom to the form y=mx+b by moving the x over to the right side. The answer is the third choice.

Answer:
either 449/25 or 11/25 depends on the -14/5 or
Step-by-step explanation:
