Lines and Circles SOLVING SIMPLE INTERSECTIONS

A Circle and Line May:  Never Intersect  1 Point of Intersection  2 Points of Intersection

Solve by Graphing  Graph the circle and the line.  Tell the point(s) of intersection as an ordered pair.  Not as exact as algebraically.

1. Solve by Graphing No point of intersection.

2. Solve by Graphing (0, 3) and (3, 0)

Solve by Algebraically  Solve the linear for a variable.  Substitute the linear into the circle  Solve for the variable.  Substitute your solution back into the linear to find the other variable.

3. Solve Algebraically

4. Solve Algebraically

Classwork  Work with a partner.  Work on both sides of the worksheet.  Get it checked off when you are finished.
