wel

Answer:

Ellipse

Step-by-step explanation:

Given the equation

4x^2 +9y^2 =36

Divide this equation by 36:

\dfrac{4x^2}{36}+\dfrac{9y^2}{36}=\dfrac{36}{36}\\ \\ \\\dfrac{x^2}{9}+\dfrac{y^2}{4}=1

The equation of the form

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1

represents an ellipse, so given equation is the equation of the ellipse.
