Find the equation of a line joining the vertex of parabola `y^(2)=8x` to its upper end of latus rectum. |
|
Answer» `y^(2)=8x` Comparing with `y^(2)=4ax` 4a=8 a=2 Co-ordinates of the latus rectum L(a,2a)=L(2,4) Co-ordiantes of vertex A=(0,0) Equation of line joining the points A (0,0) and L(2,4) `y-0=(4-0)/(2-0)(x-0)` `rArr" "y=2x`. |
