1. This is a question from integration worksheet:
1.b. Given that = 2x + 1 and that y=5 when x=1, find an expression for y in term of x.
so where do i even begin?? Can someone give me a starting point with this question please?

Don't forget your constant of integration.

Integrate indefinitely, then substitute in your x and y values to find c
4. After i integrated and substituted x and the y values in , i got c=3 so should the expression of y be y= + x + 3

Yes that's correct
