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?

\(y-x-2=0\)

\(y-3x-2=0\)

\(3y+x-6=0\)

\(16y+2x+31=0\)

\(y-8x+6=0\)

\(2y-x-3=0\)

\(y+x+2=0\)

\(y+2x+1=0\)
