From one point many lines can be passed through .
let m is the slope of line ,
then,
generl equation of line ,
( y -2) = m( x +1)
y = mx + m +2
if m = 1 then equation of line is
y = x +3
if m = -1 then equation of line ,
y + x = 1
hence, x + y = 1 and y = x +3 are two lines which is passing through (-1 , 2)
