How would I do part a, becuase we dont have a coordinate for P
Since the line is a tangent at P state the gradient of the line and you have the gradient at P.
3. You don't need the coordinate. The line is y=2x-1. What is the GRADIENT of the line?
4. Look at the marks, that's an easy indication on how much you need to do . y=mx+c, is a general equation. It tells you that it's a tangent to the point at P. So P is on that line need any more help?
