Determine the Two Equations Necessary to Graph the Ellipse with a Graphing

Question 6

Multiple Choice

Determine the two equations necessary to graph the ellipse with a graphing calculator.
- x225+(y5) 249=1\frac { x ^ { 2 } } { 25 } + \frac { ( y - 5 ) ^ { 2 } } { 49 } = 1


A) y=7122525x225y = \frac { 7 \sqrt { 1225 - 25 x ^ { 2 } } } { 25 } and y=7122525x225y = - \frac { 7 \sqrt { 1225 - 25 x ^ { 2 } } } { 25 }
B) y=25725x25y = \frac { 25 - 7 \sqrt { 25 - x ^ { 2 } } } { 5 } and y=725x2+255y = \frac { 7 \sqrt { 25 - x ^ { 2 } } + 25 } { 5 }
C) y=62549x25y = \frac { \sqrt { 625 - 49 x ^ { 2 } } } { 5 } and y=62549x25y = - \frac { \sqrt { 625 - 49 x ^ { 2 } } } { 5 }
D) y=185049x25y = \frac { \sqrt { 1850 - 49 x ^ { 2 } } } { 5 } and y=185049x25y = - \frac { \sqrt { 1850 - 49 x ^ { 2 } } } { 5 }
