Answer:
The written form would be "Nine more than three times a number is greater than -18.
Step-by-step explanation:
To graph it, you must first solve for x.
3x + 9 > -18
3x > -27
x > -9
Now we can graph this by putting an open dot at -9 and then drawing an arrow to the right.
Answer: I am so sorry if this doesn't help 135
It is parallel if the lines are in straight line next to each other, but don't cross.
It is perpendicular if these lines intersect to form right angles.
Neither if they don' t follow these rules
