This is an ellipse.
Equation of an ellipse: 
Let's find the center point first. We can do this by finding out the midpoint between the vertices or the foci.
(-9+7)/2=-1
Center: (-1,3)
Now we need to find a and b (length along x and length along y).
We know "a". It is the distance between the center and the right or left bound.
a=7-(-1)=8
To find out "b", first see that...
b^2=a^2-(distance from center to foci)^2
foci distance=3-(-1)=4
b^2=8^2-4^2
b^2=64-16
b^2=48
b=4√3
answer: 
The difference in the elevation between the canyon and the bird's nest is 737. 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- The distance below the sea level = 52 3/ 5 feet , this would take a negative value
- The distance above sea level = 789 3/ 10, this would take a positive value
Let's convert the mixed fractions to improper fraction;
= - 263/ 5 = - 52. 6 feet
789 3/ 10 = 7893/ 10 = 789. 3 feet
The difference in the elevation between the canyon and the bird's nest ;
= -52. 6 + 789. 9
= 737. 3 feet
Thus, the difference in the elevation between the canyon and the bird's nest is 737. 3 feet

Answer:
They are parallel
Step-by-step explanation:
They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts
