70-3·6+9
Remember PEMDAS.
You must multiply the 3 and 6 together, and you would get 18.
Then, you subtract 18 from 70, which would give you 52.
And finally, you would add 9 to 52, getting 61 as your final answer.
The graph is shown below.
We use an open dot at zero because x is only less than 0,
it's not less than or equal to 0.
So we have an open dot at 0 going to the left.
