The way it is written, none of them.
The "a"s cancel out.

- We need to rearrange this into
- Subtract 14x from both sides
- Divide both sides by 2
- Divide both sides by 9
- Plot the point (0, 63/9)
- Then pick some x values and put them into the equation to find the respective y values
- Then plot those points
- Finally join up those points
After solving the equation (work shown in image) your answer would be x > -2. I drew an image of how the number line should look at least similar to, using the solution.
*whenever you divide or multiply with a negative number reverse/flip the sign
< or > signs will always have an open circle
≥ or ≤ signs will have a closed/filled in circle
TIP: To know which way the arrow should point, look at the sign and think of it as an arrow.
< would have the arrow on the number point
this way: <-
or > which would have the arrow on the number line point this way: ->
