no becaus 2 times 2 is 4 so u dont add anything so its zero

You cannot solve that equation alone as it has 2 unknowns. It would need to be paired with another and share two co-inciding values so you solve them simultaneously.
(3, 1)
2x-y+4=0... what are you actually trying to find?
x = 2y = 4
18
Yes because they have the same slope
(3, 1)
x = 0 and y = 4
x = -4 and y = 2
2x-y+4=0... what are you actually trying to find?
x = 2y = 4
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
18
Yes because they have the same slope
no it equals 2x+y... lol i know its kinda confusing at first, but you should get it... lol.
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
Yes.
y=-10x-4
