+

= 1
This is because the standard form of an ellipse is

+

= 1
where a is the vertex and b is the co-vertex. So when we stick their respective x and y values in and then square them, you're left with the answer above.
The answer is number 1, y= 3x -5
Answer: 6 months i just did this
Step-by-step explanation:
-4 is the slope of the line.
hope this helps :)
let f(r)=sin^3r/cos^3r
so f(-r)= (sin(-r)/cos(-r))^3
=(-sinr/cosr)^3
=-f(r)
so it is odd function
