(5,1) y=-x+4

y=x-6

**eStone**, Monday, March 30, 2009 at 5:30pmNo, it is not because when you plug in x for the first equation you get -1 as y, not 1. And for the second equation when you plug in 5 for x you get -1 again, not 1.

**Redspider**, Monday, March 30, 2009 at 5:33pmaight the first thing u do is sub in the coordinates for x and y

so in the first equation ur x will be 5 and y will 1

then u solve the problem and both sides should be equal

so ur equation should look like this

1=5+4

1=9- as u can see both sides dont equal the same ( so it doesnt work for the first one, from there u have answered the question since it says doesn it work for BOTH solution and it doesnt)

but for practice u should try the second one

y=x+6

1=5-6

1=-1( as u can see it doesnt work for this one either, so now u have ur answer that no it doesnt work)

p.s- a solution that would work would be something like this

coordinates 1,5

y=x+4

y=5*x

cuz when u sub the x and the y they both equal 1
