Hey guy, i have my university entry test coming and i have no prep of the conic section, if any one who is an expert in this field can guide me or tell me some techniques to solve these types of questions, because i have to solve these types of questions in 60 seconds. Thanks you

for the first one, number 28 its d the correct

#

because if you put x=0 and y=3 in equation its the solution of equation

The center of the circle is the point A(1,2) the normal lines have to have this point, so point A is solution only for first equation

#

X²+y²-4x-2y+2=0 , x²-4x+4-4+y²-2y+1-1+2=0 ,( x-2)²+(y-1)²=3. Center of circle is (2,1) that is median of diameter. (2+X)/2=2 and( 3+Y)/2=1. X=2 and y=-1 other point extrem of diameter is (2,-1)
