If you plot those points, you just need to see where the extended sides intersect, or meet. (3, -8)
Can you repost with the picture please
Well just substitute y (the first equation) into the second equation.
So
5x-4(5-3x)=-3
Then just solve the equation from there.
5x-20+12x=-3
17x=17
x=1
and if you need y, y=2
I think its B im pretty sure feel free to mark me brainlyest it would mean alot. Hope this helped!
