What are the vertices of the hyperbola whose equation is = 1?

(−13, 8) and (−1, 8)

(−12, 8) and (−2, 8)

(−7, 2) and (−7, 14)

(−7, 3) and (−7, 13)

Convert –2y2 + x – 4y + 6 = 0 into standard form.

x = 2(y + 1)2 – 6

x = 2(y + 1)2 – 8

x = 2(y + 1)2 – 7

x = 2(y + 1)2 + 8

The diameter of a circle has endpoints (–3, –10) and (4, –6). What is the equation of the circle?

(x + one-half) squared + (y minus 8) squared = StartFraction 65 Over 4 EndFraction

(x minus one-half) squared + (y + 8) squared = StartFraction 65 Over 4 EndFraction

(x + one-half) squared + (y minus 8) squared = 65

(x minus one-half) squared + (y + 8) squared = 65
