Respuesta :

Answer:

A

Step-by-step explanation:

when an equation is written in slope intercept form the Y is always by itself so if you were to make A into slope intercept form you would have to subtract 1 from each side and your answer then would be y=3x-1

y+1=3x

-1     -1

y=3x-1

A is the correct answer, slope intercept is Y= mx+b
