Choose the equation of the line passing through the point (3, 2) and parallel to y = 3x  6.
y = 3x + 7
y = 3x  11
y = 3x + 11
y = 3x  12

if you compare y= = 3x  6.
with y=mx+c you get m=3
so , slope =3
and parallel lines have same slope, so your required line will be of the form
y=3x+b

now just put x=3, y=2
in y= 3x+b
and find 'b'
