thanks i got it

y^2 by rearranging the ellipse formula is 49(100-x^2)/100 when i attempt to substitute into 100y^2 - 770y = -49x^2 +98x i am still left with a y

so by using y-y1=m(x-x1) where m is -49x/100y and y1 is 7.7 and x1 is 2 i get y-7.7=-49x/100y(x-2) when rearranged that becomes 100y^2-770y=-49x^2+98x i don't think that would help

Homework Statement Find the points on the ellipse x^2/100 + y^2/49 = 1 that have tangents that pass through the point P(2, 7.7) Homework Equations The Attempt at a Solution I calculated the gradient of the ellipse which came to dy/dx = -49x/100y I then calculated the gradient of...
