Question

check whether the following pair of linear equations x=y and x-2=y-2 represents either perpendicular or coincident​

Answer 1

Given :  linear equations x=y and x-2=y-2

To Find :  check whether the linear equations are perpendicular of Coincident

Solution:

x=y

=> x  - y  = 0

x-2=y-2

=> x   - 2 - (y - 2) = 0

=> x - 2 - y + 2 = 0

=> x - y  = 0

Hence both equations are x - y = 0

Pair of linear equations are coincident
