Answer: The second graph, counting from the top.
Step-by-step explanation:
We have inequality:
-2r + 3 ≥ 19
We can isolate r in this inequality, and get:
-2r ≥ 19 - 3 = 16
-r ≥ 16/2 = 8
Now we change the sign, this also changes the direction of the greater or equal than a sign:
r ≤ -8
So we will have that our graph must start at r = -8, and include all the numbers that are smaller than -8. (including the 8)
This graph is the second one.
