12-101.

For each equation, identify the curve, write the equation in graphing form, state the locator point, and draw the graph.

1. $2x^{2} + y^{2} − 4x + 6y − 7 = 0$

Complete the squares.

$2\left(x^{2} − 2x + 1\right) − 2 + \left(y^{2 }+ 6y + 9\right) − 9 − 7 = 0$

1. $3y^{2} − x^{2} + 12y = 0$

Complete the squares. Notice that the x2 term is subtracted.
