73-76 - Identify a Conic from Its Graph Use a graphing device to graph the conic. Identify the type of conic from the graph. 73. 5x + 3y = 60 74. 9x – 12y? + 36 = 0 75. 6x + y? – 12y = 30 76. 52r? – 72xy + 73y? = 100 77-80 - Polar Equations of Conics A polar equation of a conic is given. (a) Find the eccentricity, and identify the conic. (b) Sketch the conic, and label the vertices. 2 77. r= 78. r= 1- cos 0 3 + 2 sin e 4 12 79. r = 80. r=- 1 + 2 sin 0 1- 4 cos 0
