answered Which pair of equations represents two perpendicular lines? A. y=-7/8x+3 and -7y=-8x B. 8y=3x+40 and y=8/2x-1 C. 5y=15-2x and 2/5x-4=y D. y=9x+3 and y=9x-1/3
If two lines are perpendicular, then \ (a + b = 0\) \ (2 + \left ( { – 2} \right) = 0\) Hence the given pair of the straight line is perpendicular. Q.4. Show that the equation \ (4 {x^2} + 4xy + {y^2} –
