Can someone tell me if these equations are parallel, perpendicular, intersect but not perpendicular, or coincide??

3x = 4y - 6
-4x = 3y - 6

Make them y = mx + b
4y = 3x + 6
y = 3/4x + 6/4
3y = -4x + 6
y = -4/3x + 2
They have opposite sign and reciprocal slope so they are perpendicular

Answer: perpendicular and intersect
