Given: parallel lines y = mx + c and y = mx + d

To find : distance between the parallel lines

Formula used :

The distance between the parallel lines ax + by + c =0 and ax + by + d =0 is,

D

The parallel lines are mx – y + c = 0 and mx – y + d=0

Here a = m ,b = -1 ,c = c ,d = d

D

The distance between the parallel lines y = mx + c and y = mx + d is units
