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.

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.

the answer IS "they are parallel

i just took the test and it was correct

The answer is 7. If you add everything together that she bought except the 12.75 for the shirts and subtract it from the 134.25 then you have the total that she spent on the shirts so then you divide that number by 12.75 to get the total number of shirts which will be 7.
