black hole masses and host galaxy evolution of radio
... We report new redshifts for two BL Lac objects. An uncertain redshift of 0.487 was previously reported for 1248296 (Padovani & Giommi 1995); its true redshift is 0:3819 0:0001 from fitting many absorption lines around the G band.

That is, we expect the lines expressed by the linear equations to intersect somewhere in the coordinate plane. Working from that assumption, we first try to find the value of one of the variables ( ...
