On a sheet of graph paper, or using a graphing calculator, draw the parabola $y=x^{2} .$ Then draw the graphs of the linear equation $y=x+k$ on the same coordinate plane for various values of $k .$ Try to choose values of $k$ so that the line and the parabola intersect at two points for some of your $k^{\prime} \mathrm{s}$ , and not for others. For what value of $k$ is there exactly one intersection point? Use the results of $k$ is there exactly one make a conjecture about the values of $k$ for which the following system has two solutions, one solution, and no solution. Prove your conjecture. $$\left\{\begin{array}{l}{y=x^{2}} \\ {y=x+k}\end{array}\right.$$
