Hope it helps.
For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.
For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.
Hello!! Actually I got A x = 2, y = 12.
Whenever you plug them in, 2(2) + 3(12) = 40
-2(2) + 2(12) = 20
It worked for me this way, I hope this is the right answer. Have a great day!
