1.1. The diagram shows part of the graph of  $y={x}^{2}—2x+3$

By drawing a suitable straight line, use your graph to find estimates for the solutions of ${x}^{2}—3x—1=0$

1.2. $P$ is the point on the graph of $y={x}^{2}—2x+3$where $x=2$

Calculate an estimate for the gradient of the graph at the point $P$.
