Graph the line. x+y=4

So I need to graph this. So as not to feel guilty about just taking the answer..well lets say cheatingyeah I said it (Cringe) I dont like that. but whatever I tired solving it myself.

so here is what I did.

So I think I have to substitute x and y with any variable. So this is what I got...

2+2=4

so is the point (2,2)?

I think it's a whole line so there has to be more than one point.

and you're right are the (2,2)

but there should also be (1,3) (3,1) and (4,0)

and you can keep going as long as it equals 4

like (-1,5)

after you plot the points join them up to form a line

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
