which equation represents a line parallel to the line given by y-3x=6?

A. y= -3x+4
B. y= 3x-2
C. y= 1/3x+6
D. y= -1/3x+4

The standard equation for a line is:
y = mx + b
where
m = the slope of the line
b = the y intercept

putting y - 3x = 6 in standard form:
y = 3x + 6
Therefore the slope of the line is 3. For lines to be parallel, the slope must be the same. Which of the possible answers has the same slope?
