# Integration question watch

1. The curve C with equation y=f(x) is such that
= + kx, where k is a constant.
1. Find the value of k.

so far, i have integrated to get + x squared + c.
What do i need to do to find the value of k after this?

C passes through the points(1,6) and (2,1)

Plug those two into y=f(x) and solve the simultaneous equations in and
5. K=-8
C=9
