Hi,
m1 = 4 Consider y = 4x Green line (m1 = 4 )
m2 = 0.25 consider y = highlight%281%2F4%29x Blue line (m2 = (1/4)
consider y = highlight%28-1%2F4%29x Purple line m%5B3%5D+=+%28-1%2F4%29
Note: Purple perpendicular to Green (m=4)
If lines are perpendicular, their product = to -1
Note: 4%2A%28-1%2F4%29+=+-1
