Answer:
We are given a inequality with the equality sign in terms of variable 'r' as:
![-2r+3\geq 19](https://tex.z-dn.net/?f=-2r%2B3%5Cgeq%2019)
Now we find the solution of the following inequality by solving for 'r'.
We subtract 3 from both side of the inequality to obtain:
![-2r+3-3\geq 19-3\\\\-2r\geq 16](https://tex.z-dn.net/?f=-2r%2B3-3%5Cgeq%2019-3%5C%5C%5C%5C-2r%5Cgeq%2016)
Now we multiply both side by "-1" to obtain:
![2r\leq -16](https://tex.z-dn.net/?f=2r%5Cleq%20-16)
Now on dividing both side of the inequality by 2 we obtain:
![r\leq -8](https://tex.z-dn.net/?f=r%5Cleq%20-8)
Hence, the solution of the inequality are the set of all the points on the number line which are less than equal to -8.
i.e. the shaded region is to the left of -8 and closed circle at -8.
i.e. the solution is: (-∞,-8].
Number 2 graph is the correct graph of the solution.
The two integers are -3, and -4. -3 added to -4 equals -7. -3 times -4 equals 12 as a negative times a negative is a positive.
