SLOVE 6x 3/4 =7x 1/4 -2x 1/4
3/4 1/4 => 6x 3/4 = 5x 1/4 => 6x 3/4 – 5x 1/4 = 0 => x 1/4 ( 6x ( 3/4-1/4) - 5) = 0 => x 1/4 ( 6x 1/2 - 5) = 0 => x = 0, 25/36

find the equation of a line passing through the point 3,2 and perpendicular to the line x=y
the line is y=5-x since the line is perpendicular to line y=x, the slope of this line is -1. and acc. to point slope formula i.e., (y-y’)=m(x-x’) hence (y-2)=(-1)(x-3) y-2=3-x y=5-x
