If the abcissa and ordinate are equal , find the point where x+2y = 12.
Given x= y
Hence 3 y= 12
y = 4
So the point is (4,4)
The abcissa & ordinate of a point passing through 7x-4y + 6 = 0 , are equal . Find the point.
Find a point on the line x + 2y = 9 where the ordinate is equal to the abscissa
The sub-normal at any point of the curve x2y2=a2(x2−a2) varies as
