whose roots arem=1,-1/7so possible values of L1 arex=y andx = -7y

squaring and simplifying we get the quadratic as

It’s simpleLets say L1 is y=mxThen as chords are equal the perpendicular distance from the center of the circle should also be samecenter is(1/2,-3/2)so we have (by equating the perpendicular distance from center to L1 and L2)
