Answer 11

for two lines to be coincident they must pass through same points all the time.
so the coefficients of both the lines have to be of the same ratio.
if ax+by+c=0 and dx+ey+f=0 are coincident then a/d=b/e=c/f

Answer 13

@KendrickLamar2014 help.

Answer 14

Coincident means they are the same line.
-2x + 5y = -12 - (you want to get -6x, so multiply everything by 3). Which equals:
-6x + 15y = -36
