Eq of tgt to parabola y = x^2 is ( y + y1 )/2 = x x1, where ( x1, y1 ) = ( a, a^2 ), i.e., y + a^2 = 2 x ( a ) i.e., y = 2ax - a^2. ...................Ans. ........................................................................................... You would love this : To write the eq...

Line parallel to 9x - 2y = 5 has eq 9x - 2y = c.....( 1 ) If it passes thru' ( 9, - 4 ), then 9 ( 9) - 2( - 4) = c so that c = 89. Hence, from (1), the req'd equation is : 9x - 2y = 89. ................Ans.

Correct Option is ( b).

Ok Robyn, I don't know which grade you are in. If u know Finite Differences, then by a simple use of Newton's Forward Interpolation, the answer to the first part is f ( x ) = 5 + ( x / 2 ). Of course, the same answer can also be obtained by common sense.
