The circle given by x² + y^2 - 2y- 11 = 0 can be written in standard form like this: x^2(y – k)^2= 12
What is the value of k in this equation?

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3
