Graphing Circles & Writing Equations Skills Check
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
