Best ResponseYou've already chosen the best response.0Do you want me to show you how i got to my answer?

anonymous

Best ResponseYou've already chosen the best response.0ok, so i found the equation for the first line as y=3x+6, which i showed you previously

anonymous

Best ResponseYou've already chosen the best response.0the equation for the second line is y=2x+1, using the same method as the equation for the first line

anonymous

Best ResponseYou've already chosen the best response.0now we need to find what x and y are

anonymous

Best ResponseYou've already chosen the best response.0so we replace y in the first equation with 2x+1 and solve for x

anonymous

Best ResponseYou've already chosen the best response.0Ok I was trying to figure out x and y too.

anonymous

Best ResponseYou've already chosen the best response.0solving for x i got x=1

anonymous

Best ResponseYou've already chosen the best response.0Do you agree with the answer?

anonymous

Best ResponseYou've already chosen the best response.0Ok, but wouldn't be 9 though,b/c of the yintercept.

anonymous

Best ResponseYou've already chosen the best response.0what do you mean? are you talking about the equation for the first line?

anonymous

Best ResponseYou've already chosen the best response.0ok, theres an easy way to see if the equation is correct or not

anonymous

Best ResponseYou've already chosen the best response.0so you think the equation is y=3x+9 correct?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok, so you plug in a point and see if both sides of the equation are equal

Best ResponseYou've already chosen the best response.0does 3(1)+9 equal 9?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so that equation is incorrect lets try my equation

anonymous

Best ResponseYou've already chosen the best response.09=9 so the equation works

anonymous
