Question 1136091

Vertical will mean we will look for the larger denominator value under the {{{y^2}}} term.

=>major axis of length: {{{2a=18}}}=>{{{a=9}}}
=>minor axis of length:{{{2b=10}}}=>{{{b=5}}}

{{{x^2/b^2 + y^2/a^2 = 1}}}

{{{x^2/25 + y^2/81 = 1 }}}


C.x squared divided by twenty five plus y squared divided by eighty one = 1
