No (4) Find the centre & radius of each of the following
x?+ y2- 2x + 4y - 4 = 0
Vo. (5) If ( x-1, y+4 ) = (1, 2) find the values of x&y​

Answer 1

Answer:

the lines 3x + 4y 12 and Consider a variable line L which passes through the point of intersection P of x + 2y-5 = 0 meeting the coordinate axes at points A and B.
