Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
The length is going to equal four times the width plus two, as the situation states.
L(w) = 4w + 2
2x^2-4x-12

<u>Answer:
</u>
The center, vertices and foci of the ellipse with equation
respectively
<u>
Solution:
</u>
The equation of ellipse with centre (0, 0) in the form of
--- eqn 1
Where,
x is the major axis
Centre (0, 0)
Vertices is
Foci is
where 
Now given that the equation of ellipse is
--- eqn 2
On dividing equation (2) by 36,

On comparing equations (1) and (2),
We get a = 3, b= 2

So centre of 
Vertices of 
Foci of
