Question
CBSEENMA11015149

Find the coordinates of vertex, focus, equations of axis, tangent at vertex, directrix, latus rectum of the following equation:
9 straight y squared plus 25 straight x equals 0


Solution

Solution not provided.
Ans. Vertex - (0, 0)
       Focus - space space open parentheses negative 25 over 36 comma space 0 close parentheses
       Axis - (y = 0)
       Tangent at vertex - (x = 0)
       directrix - space space space space straight x minus 25 over 36 equals 0 space or space 36 straight x minus 25 equals 0
       latus rectum - space space space 25 over 9
