Question

Which statement explains how the lines x − y = 2 and y = x + 1 are related? They are parallel. They are perpendicular. They are the same line. They are not related.

Answer 1

Answer:

the answer IS "they are parallel

Step-by-step explanation:

i just took the test and it was correct

Answer 2

Answer:

They are parallel.

Step-by-step explanation:

L1: x − y = 2 ; or x-y-2=0

L2: y = x + 1; or x-y+1=0

The slope of the line  L: ax+by+c=0 is  m=  -a/b.

L1: x-y-2=0=> m1=(-1)/(-1)=1

L2: x-y-1=0=> m2=(-1)/(-1)=1

L1 and L2 have the same slope; m1=m2=1

=> L1 and L2 are parallel.
