\(y-2x=-1\) \(x+3y=4\) Multiply the second one by \(2\) and we get \(y-2x=-1\) \(2x+6y=8\) now add them together \(7y=7\) so that \(y=1\) and now we find \(x\). \(x+3(1)=4\implies x=1\)

\((-1,1)\) is not their intersection. Make sense?

so its either the second or third one

at the intersection the (x, y) given (-1, 1) satisfies both equations
zzr0ck3r

\(1-2(-1)\ne -1\)

\((-1,1)\) Does NOT satisfy either equation @triciaal

graph of two lines, one with a positive slope and one with a negative slope, that intersect at the point (negative 1, 1) I misunderstood then so is the question incomplete?

is it correct
triciaal

@GiulianaRestrepo we can't see your choices. the solution is the graph where the (x, y) satisfies both equation

sketch each graph on the same grid and find the point where they meet
triciaal
  • triciaal
the first equation y = 2x -1 hint slope 2 and point (0, -1) is on that line the 2nd eqn 3y = -x + 4 slope negative and when y = 0 x = 4 so (4, 0) is on that line can you sketch each line and find (x, y) where they meet?
