Answer

$(0,1)$ and $(1,2)$

Work Step by Step

$\left\{\begin{array}{l}{y=x^{2}+1} \\ {y=x+1}\end{array}\right.$ Graphed with desmos.com/calculator. Subtracting the equations, $0=x^{2}+1-x-1$ $0=x^{2}-x$ $0=x(x-1)$ $\left[\begin{array}{lll} & x=0 & x=1\\ \text{back-substitute: } & y=(0)+1 & y=(1)+1\\ & y=1 & y-2\\ & & \\ & (0,1) & (1,2)\\ & & \end{array}\right]$
