3,-18,-10,-1
y-10%3E2y-3....plug in 3
3-10%3E2%2A3-3
-7%3E6-3
-7%3E3..........the number 3 is NOT solution of the inequality


y-10%3E2y-3....plug in -18
-18-10%3E2%2A%28-18%29-3
-28%3E-36-3
-28%3E-39..........the number -18 IS solution of the inequality


y-10%3E2y-3....plug in -10
-10-10%3E2%2A%28-10%29-3
-20%3E-20-3
-20%3E-23..........the number -10 IS solution of the inequality


y-10%3E2y-3....plug in -1
-1-10%3E2%2A%28-1%29-3
-11%3E-2-3
-11%3E-5..........the number -1 is NOT solution of the inequality
