Question

draw the graph of linear equation 2x+y=0​

Answer 1

the graph of linear equation is 2x+y=0

2x=-y

ifx=1,2,-1,-2.

if x=1,2(1)=-y

y=-2 ,the point is (1,-2)

if x=2 ,2×2=-y

y=-4,the point is (2,-4)

if=-1,2(-1)=-y

y=2 ,the point is (-1,2)

if x=-2,2(-2)=-y

y=4,the point is (-2,4).

mark these points on the graph of carti siean plane.
