a) b) c) d) Confirm that line I is a normal to the curve y = x +1 at point P. Other than at point P, will line I meet the curve y = x+1 again? Explain your answer. There are two points on the curve y = x +1 where the gradient is 12. Find the coordinates of each point. Find the area, which is shaded on the diagram, that is bounded by the x- and y-axes, line 1 and the curve y = x +1. P(2, 3) Figure 3 NOT TO SCALE Q(11,0) Figure 3 shows the curve y = x + 1. Line I is also shown which intersects with the curve at point P(2, 3) and the x-axis at point Q(11, 0).
