Question

Find the value of k. If the lines 2y = 5x+k touches the parabola y2 =6x
Find the equation of a parabola whose focus is S(1.-7) and vertex is A(1.-2)
(1/2,2) is one extremity of a focal chord of y2= 8x. Find the other extremity.
If the chord joining the points t1 and t2, on the parabola y = 4ax is a focal chord then show that t1t2=-1.​
