Answer:
-3 > x
Explanation:
-7x > 21
___ ___
-7 -7
x < -3
Now, whenever we divide or multiply by a negative, we reverse the inequality symbol.
In order to graph this, you do what I call the zero-interval test, which in this case, we plug in 0 for x, and determining whether the statement is false or true, determines which side we shade:
0 < -3 [Since this is a false statement, instead of shading to the right, we shade to the left.]
I am joyous to assist you anytime.
