um.. I am having trouble with a question I started some work and then I am not sure if I am doing it right! and if I am I don't know what to do next!
anyways here is the question that stumps me!
An ellipse is formed by strecthing the grapgh of x^2+ y^2=1 horizontally by a factor of 3 and vertically by a factor of 4. Determine the equation of this ellipse in standard form.
so my work:
x^2/9 + y^2/16=1
am I going on the right track or am I totally off? if I am doing this right were do I go from here?
