Answer:

irst, solve for two points which solve the equation and plot these points:

First Point: For

x

=

0

f

(

0

)

=

(

2

0

)

3

f

(

0

)

=

0

3

f

(

0

)

=

3

or

(

0

,

3

)

Second Point: For

x

=

2

f

(

2

)

=

(

2

2

)

3

f

(

2

)

=

4

3

f

(

2

)

=

1

or

(

2

,

1

)

We can next plot the two points on the coordinate plane:

graph{(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y + 2x + 3)(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}
