The length of the semi-major axis of the ellipse is 7.
What is the semi-major axis of an ellipse?
The semi-major axis of an ellipse is the half of the longest diameter passing through its vertex and focus.
The general equation of an ellipse is :
⇒ x²/a²+y²/b²=1, where a is the semi-major axis and b, is the semi-minor axis
x²/49+y²/36=1
x²/(7²)+y²/(6²)=1
x²/a²+y²/b²=1
a=7

<u>Algebra I</u>
- Slope Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Slope 1</em>
Point (-2, 3)
Point (1, 3)
<em>Slope 2</em>
Point (4, 21)
Point (9, 46)
<u>Step 2: Find slope </u><em><u>m</u></em>
<em>Slope 1</em>
- Substitute:

- Subtract/Add:

- Divide:

<em>Slope 2</em>
- Substitute:

- Subtract:

- Divide:

We know that 5 is greater than 0. ∴ Slope 2 is bigger than slope 1.
The difference is one has bigger fractions and the other one has different quantities which can be divided by pie = 3.4 squared into a rectangle which equals a+b=c squared
