Answer 2

ok do u know how to solve without calculator?

Answer 3

y = -3x
y = -4x +2
Put x = 0 , 1 , 2 for few points to graph y.

Answer 4

please, note that 1) if we set x=0 in your equation, we get y=2, and so the point (0,2)
2) if we set y=0 in your equation, we get x=1/2, and the point (1/2,0)
so the graph of your equation: 4x+y=2, is a line joining the points A=(0,2) and B=(1/2,0) each other

Answer 5

sorry an infinite line, of course

Answer 6

the graph of the equation y=-3x, is an infinite line which passes through the origin of the coordinate system and the point (1,-3)
