Q20 of 62 Page 11

Find the coordinates of the focus, axis of the parabola, the equation of the directrix and the length of the latus rectum. y2 = 10x


The given equation involves y2, so the axis of symmetry is x-axis

y2 =

The coefficient of x is positive, so the parabola opens to the right.

Focus = , equation of directrix is x = and length of latus rectum = 4a =
4 × = 10, equation of the axis is y = 0.
