Equation of a line

How to find the value of p if the lines 3x - py = 6 and 6x + 3y + 2 = 0 are parallel?

Please advise. Thanks

parallel means same gradient

change both to the form y = mx + c

equate the 2 different m to find the answer :D

Sorry, I still don't get it. How do you equate the 2 different m together?

3x - py = 6
y = (3/p)x - 6/p

6x + 3y + 2 = 0
y = -2x - 2/3

Since they are parallel, gradient is the same

3/p = -2
p = -1.5
