thanks Mr. Tom for replying me but i wanna more disscus for it cause i didnt got U the question says that y intercept 6 so U mean that it intercept the line at (0,6) i think that this also means the f(x) which is y is equal 6 so i can subsititue y by 6 so PLZ Mr.Tom clarify it more cause i am confused about this question thanks in advance

Hi all how is everyone hope good and fine i am new here but really a good forum which share very very big and important knowlegde a small problem face me in get a solution for the question: -if tangent line to the ellipse 9x^2 + 4y^2 = 36 has y intercept 6 find the equation of the tangent. the problem is when we substitute y by 6 and try to get a value for x the equation will be as follow x^2 = -12 the problem is there is no roots for a negative number otherwise we use an imaginry numbers hope anyone could help me to a get a solution for that question thanks in advance
