Answer:

Step-by-step explanation:
For this case we have this point given (5,-3) and we want to create an slope intercept formula given by:

And this equation needs to be parallel to y= 3x-1 so then the slope needs to be equal m =3 and then we can use the point given to find the intercept b like this:


And the formula for the slope would be given by:

The answer is A since: 3^2+4^2=5^2
25=25
