To practice writing the equations of vertical parabolas, write the equations of these parabolas in vertex form: • focus at (-5,-3), and directrix y = -6
• focus at (10,-4), and directrix y = 6.

Read the situations in the table below. then drag a graph and equation to represent each situation. indicate whether each of the relationships is proportional or non-proportional. edit : i got the right answer its attached
