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+ y^2=1

(x/3)^2 +(y/4)^2=1

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?
