anation:
one way is to find the intercepts, that is where the graph
crosses the x and y axes
∙
let x = 0, in the equation for y-intercept
∙
let y = 0, in the equation for x-intercept
x
=
0
⇒
y
=
0
−
2
⇒
y
=
−
2
←
y-intercept
y
=
0
⇒
2
x
−
2
=
0
⇒
x
=
1
←
x-intercept
plot the points
(
0
,
−
2
)
and
(
1
,
0
)
draw a straight line through them for graph
graph{(y-2x+2)((x-0)^2+(y+2)^2-0.04)((x-1)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
