Answer:
2nd graph is correct
Explanation:
solve the inequality
- 3x - 7 < 20 ( add 7 to both sides )
- 3x < 27
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x > - 9
since > then open circle at - 9 on the number line
the arrow head will point to the right indicating values > - 9
this is shown on the 2nd graph
