Solve the system y = 2x + 6 and 3y = 6x + 18 by using graph paper or graphing technology. What is the solution to the system?

Question

anonymous · Answer

infinity solutions they're the same line... if you look at your equations

3y=6x+18
y=2x+6

the top if you divide by 3, you get the bottom. Therefore it's the same line

if you put a line on top of another line how many times would they hit

if you want to go more into detail you can create a parameter by allowing x=t

if x=t, 

y=2t+6

{t,2t-6} would be the answer to every solution... but i don't think it's necessary
