Question 757694: Determine whether the given point is a solution to the linear inequality.
x - y ≤ 8: (1, -9)
1-9= -8 so -8 is not a solution because it is lower than 8.
Please let me know if this is correct. Thank you.

Well, IF and represent the coordinates of the point , AND IF did indeed equal -8, then the ordered pair would be a solution of the inequality precisely because -8 is less than 8. However, your argument falls apart because you did not do the substitution of values correctly. so substituting into must result in which is equivalent to and since 10 is NOT less than or equal to 8...
