The graph represents a vertical ellipse with centre (h,k)=(0,-2)
Length of major axis, 2a =6, that gives, a=3
And length of minor axis, 2b =2, that gives b=1 .
The equation of vertical ellipse is
Substituting the values of h,k,a and b, we will get
Answer:
-21x+7
Step-by-step explanation:
Let's see here.
y=1/3-1/21x
switch x and y and vice versa
x=1/3-1/21y
y=-21x+7
1200 squares because, 3 m = 300 cm and a square has 4 sides so you times 3 and 4 and you get 12 so 12 m = 1200 cm
