The slope of line a is triple the slope of line b. The slope of line c is half of the slope of line b. The slope of line d is 3 less than quadruple the slope of line c.. The equation of line a is 3y-36x=24. What is the slope of line c?
a--> 3y=36x+24 --> y=12x+8 --> slope=12
12=3b --> b=4
c=b/2 --> c=4/2 --> c=2
