Best ResponseYou've already chosen the best response.0Hi Welcome to Openstudy @mathsucks_0 :) First thing you need to know is the slope intercept form: \(\sf y=mx+b\) where m is the slop and b is the yintercept. Next thing you need to do is determine the slope of x+y=12, do you know how to do it?

Best ResponseYou've already chosen the best response.0For slope I got 2/3.. is that correct?

Best ResponseYou've already chosen the best response.0let's see.. i'll change it to slope intercept form, which will be: 3x+y=12 y=3x+12 m=3 and b=12 the intercept for this equation is 3. Now, since the line that you are looking for is PARALLEL to the given equation, they will have the SAME slope. So plug m=3 in the equation y=mx+b, what will you get for this part ?

Best ResponseYou've already chosen the best response.0right :) Using your given point (3,8), we can now solve for the yint or b in the equation. Plug in x=3 and y=8, then solve for b

Best ResponseYou've already chosen the best response.0y=3x+b 8=3(3) + b > plug in the points b= 83(3) > evaluate to solve for b what will you get?

Best ResponseYou've already chosen the best response.0I see what I did wrong, I missed where you wrote to plug in for x

Best ResponseYou've already chosen the best response.0i'm glad that you are figuring out where you did wrong ^_^ that's a good habit for students! anyway, we're almost done so m=3, b= 1 y=mx+b, put the values of m and b in the equation and you'll get?
