Ive attached the full question

I have calculated part a) as $-3i + j$ is this right???

Then assuming this is correct i assume the normal is $3i - j$

How do I calculate the equation of the line, directional dirivative and the value of the line intergral. . . i have looked over my notes and I understand the basic theroy just unsure on how to calculate the values

Any ideas??
