Question 698405
write the equation for the graph with vertex (-2,-7) and focus (1,-7)
**
This is a parabola that opens right.
Its standard form of equation: (y-k)^2=4p(x-h), (h,k)=(x,y) coordinates of the vertex
For given parabola:
given vertex: (-2,-7)
axis of symmetry: y=-7
p=3 (-2 to 1) (distance from vertex to focus on the axis of symmetry)
4p=12
equation: (y+7)^2=12(x+2)
