First, find the equation's two solution points and plot them on the graph.
First Point:
For x = 0
( 2 0 ) + y = - 1
0 + y = - 1
y = - 1 or ( 0 , - 1 )
Second Point:
For y = 0
2 x + 0 = - 1
2 x = - 1
2 x 2 = - 1 2
x = - 1 2 or ( - 1 2 , 0 )
We can next graph the two points on the coordinate plane:
graph{(x^2+(y+1)^2-0.025)((x+1/2)^2+y^2-0.025)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(2x+y+1)(x^2+(y+1)^2-0.025)((x+1/2)^2+y^2-0.025)=0 [-10, 10, -5, 5]}
