Two lines have equations and 2x-3y+6=0 and 4x-6y+k=0
b. For what value of k will these lines be coincident?

since they are collinear of each other, would I just say k=12 because 2x doubled is 4x and -3y doubled is 6y and 6 doubled would be 12?

"just so" means yes, you are correct.
sorry for my sophisticated language ...
