Answer:
- The graph has an open circle at 7.
- The arrow points left.
Step-by-step explanation:
Adding 10 and dividing by 4, we have ...
4x < 28
x < 7
The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.
- The graph has an open circle at 7.
- The arrow points left.
