    A) y=3x+6

    Step-by-step explanation:

    A line's equation is written as y=mx+b where m is the slope and b is the y-intercept. If the line has the same slope as y=3x then m=3. It also crosses 6 units above y=3x. y=3x crosses at (0,0) since b=0 so b=6 in the other line. This means the equation is y=3x+6.
