15. Angio is multiplying the -2 to the linear inequality of two variables, 4x – 6y ≥ 5 and his answer is -8x + 12y ≤ -10, is he right?
a. No, because multiplying a negative integer doest not change the inequality symbol.
b. No, because multiplying a negative integer reverses the direction of the inequality symbol.
c. Yes, because the product of the terms is correct and the inequality symbol does not change.
d. Yes, because the product of the terms is correct and the direction of the inequality symbol is reversed.
