Yon can easily see what happens when you notice that the only difference between the two linear equations is y-intercept.
Notice that both equations are in the slope-intercept form: y = mx+b and, in both equations, the slope (m =3) is the same.
So the lines are parallel with the first one crossing the y-axis at y = -2 (b= -2), while the second one crosses the y-axis at y = 6 (b = 6)
Let's confirm this by graphing both equations.
y = 3x-2 (Red line)
y = 3x+6 (Green line)
