Two parabola have the same focus. If their directrices are the x-axis and the y-axis respectively, then the slope of their common chord is :

Two parabolas have the same focus. If their directrices are the x-axis & the y-axis respectively, then the slope of their common chord is

Two parabola have the focus (3, 2). Their directrices are the x-axis and the y-axis respectively. Then the slope of their common chord is

Wrtie the slope of X-axis and Y-axis .

The parabola having its focus at (3,2) and directrix along the y-axis has its vertex at

Two unequal parabolas have the same common axis which is the x-axis and have the same vertex which is the origin with their concavities in opposite direction.If a variable line parallel to the common axis meet the parabolas in P and P' the locus of the middle point of PP' is

Let there be two parabolas with the same axis, focus of each being exterior to the other and the latus rectam being 4a and 4b. The locus of the middle points of the intercepts between the parabolas made on the lines parallel to the common axis is a:

Two parabola with a coomon vertex and with axes along x-axis and y-axis, respectively intersect each other in the first quadrant . If the length of the latus rectum of each parabola is 3 , then the equation of common tangent to the two parabola is
