  2. Ex 1) Write an equation of an ellipse with x-intercepts and y-intercepts 3 is bigger # on y- axis on x- axis

  3. Ex 2) Find an equation of an ellipse having foci (-3, 0) and (3, 0) and sum of focal radii equal to 12 Sum of focal radii = 2a Foci are ± c on x- axis on x- axis foci on same axis as ‘a’

  4. Homework #907 Pg. 421 7 – 13 odd (Graph & find x-int, y-int, coord of foci, identify major axis, length of major axis, and eccentricity) Pg. 422 15 – 22 all
