#### Solution Preview

The parabola is of the form y^2 = 4ax
Focus is given by (a, 0) = (-5, 0)  a = -5
The parabola is y^2 = -20x
Equation of the LR is x = -a
The equation is x = 5
Two points on the LR can be taken as (5, 1) and (5, 4)

#2 Find the equation of the parabola. Find 2 points that define latus rectum. Graph. Focus (0,1) Diectrix line y= -1

The parabola is of the form x^2 = 4ay
Focus is at (0, a) = (0, 1)  a = 1
The equation of the parabola is x^2 = 4y
Two points on the LR can be taken as (2, -1) and (4, -1)

#3. Find the equation of ellipse.draw the graph.
