Answer:
(0,-7)
Explanation:
Hey There!
So we can easily find which one is a solution but taking an order pair and plugging in the x value
then we solve for y and if we get the value of y that is with the matching x value then it is a solution
for example for the first pair we plug in -1 to x
-1-7=-8
-8 does not equal -6 therefore the first one is not a solution
for the second one we plug in 0 to x
0-7=-7
-7=-7 therefore it is a solution
but lets just check the rest to be safe
for the third one we plug in 8 to x
8-7=1
-1 does not equal 1 thus it is not a solution
for the last one we plug in -1
-1-7=-8
-8 does not equal 6 therefore it is not a solution
so we can conclude that the second one is a solution
