How do I find the major axis of the ellipse 4x^2+25y^2 = 100
I found that it's a horizontal because it becomes: x^2/25 + y^2/4 =1
However, I still don't kno whow to find the major axis, could someone help please?
the larger number is under the x, so the major axis is the horizontal axis. it will be the line y = 0. the vertices on this axis will be (-5,0) and (5,0)
