1)Write an equation for an ellipse if the endpoints of the major axis are at(1,6)and (1,6)and the endpoints of the minor axis are at (5,0)and (3,0)
answer= (x1)^2/36+y^2/16=1
2)Which is the equation of an ellipse with center (4,2)and a horizontal major axis?
answer= (x4)^2/16+(y2)^2/4=1
3)Find the center and radius of the circle with equation x^2+(y4)^2=9
answer= (0,4);3
4)Write the equation x^22x+y^2+4y=11 in standard form.
answer= (x1)^2+(y+2)^2=16
5)Write the equation 4x^2+24xy+34=0 in standard form
answer= y= 4(x3)^2+2
#3  correct
