1. the equation of a circle is x ^2 + y ^2 β 4 x + 2 y = 11 . what are the coordinates of the center of the circle? question 1 options (2, β1) (4, β2) (β4, 2) (β2, 1) 2. what is the equation of the circle with center (4, -3) and radius 2? question 2 options: (x + 4)^2 + (y β 3)^2 = 4 (x + 4)^2 β (y β 3)^4 = 4 (x β 4)^2 + (y + 3)^2 = 2 (x β 4)^2 + (y + 3)^2 = 4 3. what is the equation of this circle? (has picture) (x β 2)^2 + (y β 7)^2 = Β½ (x + 2)^2 + (y + 7)^2 = ΒΌ (x + 7)^2 + (y + 2)^2 = ΒΌ (x + 2)^2 + (y + 7)^2 = Β½ 4. what are the center and radius of the circle described by the equation x2 + y2 β 18x + 12y + 68 = 0? question 4 options: center (-9, 6); radius 7 center (9, -6); radius 7 center (-6, 9); radius 7 center (6, -9); radius 7 5. select the equation of a circle with center (-3, 7) and radius 5. question 5 options: (x - 3)^2 + (y + 7)^2 = 25 (x + 3)^2 + (y - 7)^2 = 25 (x + 3) + (y - 7) = 25 (x - 3) + (y + 7) = 25
