x%5E2%2F16%2By%5E2%2F9=1
x-intercept occurs when y+=+0, so set y+=+0 and solve for x:
x%5E2%2F16%2B0%5E2%2F9=1
x%5E2%2F16=1
x%5E2=16
x=sqrt%2816%29
solutions:
x=4 and x=-4
so, x-intercepts are at (4,0) and (-4,0)

y-intercept occurs when x+=+0, so set x+=+0 and solve for y:
0%5E2%2F16%2By%5E2%2F9=1
y%5E2%2F9=1
y%5E2=9
y=sqrt%289%29
solutions:
y=3 and y=-3
so, y-intercepts are at (0,3) and (0,-3)
