First, let's find the inequality:
"15 less than or equal to -10x."
We can write in math "less than or equal to" as ≤.
So, we can write the next inequality:
15≤-10x
Solve for x
(-1)15≤(-1)-10x
-15≥10x
Then
-15/10≥x
-3/2≥x
Now, the graph will take all the x values less than or equal to -3/2.
The graph is the next:
