Question 3
Rewrite the following equation of a circle to the standard form: x 2 + y 2 + 10x - 6y + 4 = 0

(x-5) 2 + (y + 3) 2 = 26

(x + 5) 2 + (y-3) 2 = 26

(x + 5) 2 + (y-3) 2 = 30

(x-5) 2 + (y + 3) 2 = 30


Question 4
Find the vertex and the focus of the following parabola: x 2 -4y-4 = 0

V: (0,1) F: (0, -2)

V: (0,1) F: (0, -1)

V: (0, -1) F: (0,0)

V: (0, -1) F: (0,2)
