This is an equation of a circle centered at point (0,0) with radius 1.
This is an equation of a line with slope m=-1 and y-intercept at b=-1 or at point (0,-1).
Step 1. Let's solve for x in
Subtract -y to both sides of the equation
Step 2. Substitute
Step 3. Subtract 1 to both sides of the equation
Step 4. Find x-coordinates when
. One intersection point is (-1,0).
. One intersection point is (0,-1).
Step 5. Then intersection points are (-1,0) and (0,-1)
Here are the graphs of the circle and line and note they have two common points.
I hope the above steps were helpful.
