The top of the packet says "sketch the graph by finding the vertex and the point M and M' ( the reflection of M) as defined in the diagram above. Use the geometric definition of a parable to find the equation of these parables." 

Than it gives me the directrix and the focus. The first graph on the page, or question 11. says Directrix Y=9, Focus A(-3,7). Than it asks for the vertex and equation above the blank graph.
