Write an equation of the liine that pass through point P and is perpendicular to the line with the given equations P(0,0),y=-9x-1

Answer 1

The slope of the given line is -9

The slope of the perpendicular line is 1/9 (as the product of the slopes has to be -1)

So y = (1/9) x + b

x = 0, y = 0, so 0 = 0 + b, so b=0

So y = (1/9) x is required equation
