Which line is parallel to the line Y = X +7?
A. X-y=5
B. X+y=-2
C. Y=1
D. X=1

a

Step-by-step explanation:

y=1 has a slope of 0,

x=1 has an indefinite slope,

x+y has a negative slope, so

x-y would be the only oneeft

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
