To solve the inequality \( 8y - 2 \leq -10 \), follow these steps:
1. **Isolate the variable \( y \)**:
Add 2 to both sides:
\[
8y - 2 + 2 \leq -10 + 2
\]
Simplifying gives:
\[
8y \leq -8
\]
2. **Divide by 8**:
Divide both sides by 8 (note that since 8 is positive, the inequality direction will not change):
\[
y \leq -1
\]
So, the solution to the inequality is:
\[
y \leq -1
\]
### Graphing the Solution
1. **Plot the point** \( -1 \) on a number line.
2. **Since the inequality is \( \leq \)**, use a **closed circle** on \( -1 \) to indicate that this value is included in the solution.
3. **Draw a ray** to the left of \( -1 \) to indicate that all values less than \(-1\) are also included in the solution.
This graphic representation shows that all numbers less than or equal to \(-1\) satisfy the inequality.
If you were creating the graph visually, it would look like this:
```
<---•=========================
-2 -1 0 1
```
Here, the dot at \(-1\) is filled in, indicating that \(-1\) is included in the solution. The line continues to the left, showing all values less than \(-1\).
