## Perpendicular Lines and Slopes

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} –

## Determine whether each pair of equations represents

So these two lines are perpendicular. Now, if two lines are perpendicular, if the slope of this orange line is m-- so let's say its equation is y is equal to mx plus, let's say it's b 1, so it's some y

## A lot of happy students  ## Which pair of equations represents two perpendicular

1) 2x 2 = 2y (2x + y) 2) x 2 + y 2 + 3 = 0. 3) 2x 2 = y(2x + y) 4) x 2 = 2 (x – y) Solution: If a pair of straight lines are perpendicular to each other, then coefficient of x 2 + coefficient of y 2 = 0.
