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?

determine point of intersection of the given lines, if an intersection does exist L1: (x,y,z) = (4,-3,15) + t(6,-3,12) L2: (x,y,z) = (-2,1,-4) + s(-2,1-4) I was able to get this 4+6t=-2-2s -3-3t=1+s 15+12t=-4-4s but then i got stuck because i couldnt get...

sorry? am I in the correct for thinking this?

not 100 percent about this but here goes. 9:50am-3:12pm=5:22min=5.36666hrs 24hr=360degrees (5.36666x360)/24= 80.50degrees difference
