It's not so much that the two equations are of different orders We could differentiate both sides of the first equation and get a secondorder equationIf the circles x 2 y 2 5Kx 2y K = 0 and 2(x 2 y 2) 2Kx 3y – 1 = 0, (K ∈ R), intersect at the points P and Q, then the line 4x 5y – K = 0 passesSolving the above equation, we get x 2 y 2 =4 We can write the above equation as (x0) 2 (y0) 2 =4 Compare the above equation with the standard form, we get h=0,k=0 and r 2 =4 r=√ 4 =2 Now, we can plot the circle on the graph paper with radius r = 2 and center (0, 0) Example 3 Find out the radius and center of a circle from the
