Question 1061527
Hi, can you please help me on how to graph this equation manually? Thank you!

{{{ x^2+4y^2=16 }}}
<pre>The very, very, very first thing you need to do when GRAPHING an equation is to DETERMINE the type of graph that the equation REPRESENTS. 
You might not be able to graph any equation, unless of course you're using a graphing calculator or an online site that can graph the
equation for you. Doing it manually though, I already told you the 1st thing you need to do.
Hint: The fact that the 2nd degree variables have same-sign (+) but different coefficients (1 and 4) on them, means that this equation represents an ELLIPSE.
You need to now research how to go about manually graphing an ELLIPSE.
