Review Graphing Equation of Circles /Standard Form
1) Sketch the circle whose equation is: x2 + (y – 2)2 = 16
Directions 2-5: Write the given equations in center- radius form and identify the center
and radius of the circle:
2) x2 + y2 – 2x - 8y + 1 = 0
3) x2 + y2 + 10x + 9 = 0
4) x2 + y2 – 2x - 6y -15 = 0
5) 3x2 + 3y2 – 6x + 12y - 9 = 0
6) Write the equation of the circle given its graph
7) Solve systems of equations algebraically:
y = x2 – 8x + 6
2x – y = 10
8) Solve for the zeroes algebraically: 6x2 - 13x + 2 = 0
