Warm-up

Below are eight equations of straight line graphs.

• Which lines are perpendicular to each other?

• Can you find the coordinates of the point where each pair of perpendicular lines intersects?

$y-x-2=0$

$y-3x-2=0$

$3y+x-6=0$

$16y+2x+31=0$

$y-8x+6=0$

$2y-x-3=0$

$y+x+2=0$

$y+2x+1=0$
