Graph shape: a straight line for y = -3x, passing through the origin and decreasing from top-left to bottom-right; position_hint=center
1. **State the problem:** We are given the function $$y = -3x$$ and need to fill in the table of values for $$x = -3, -2, -1, 0, 1, 2, 3$$ and then use these values to graph the function.
2. **Formula used:** The function is linear and given by $$y = -3x$$. This means for each value of $$x$$, multiply by $$-3$$ to find $$y$$.
3. **Calculate each value:**
- For $$x = -3$$: $$y = -3 \times (-3) = 9$$
- For $$x = -2$$: $$y = -3 \times (-2) = 6$$
- For $$x = -1$$: $$y = -3 \times (-1) = 3$$
- For $$x = 0$$: $$y = -3 \times 0 = 0$$
- For $$x = 1$$: $$y = -3 \times 1 = -3$$
- For $$x = 2$$: $$y = -3 \times 2 = -6$$
- For $$x = 3$$: $$y = -3 \times 3 = -9$$
4. **Completed table:**
| x | y = -3x |
|----|---------|
| -3 | 9 |
| -2 | 6 |
| -1 | 3 |
| 0 | 0 |
| 1 | -3 |
| 2 | -6 |
| 3 | -9 |
5. **Graph shape explanation:** The graph is a straight line passing through the origin $$(0,0)$$. Since the slope is $$-3$$, the line decreases steeply from top-left to bottom-right.
6. **Summary:** We found the $$y$$ values by multiplying each $$x$$ by $$-3$$ and confirmed the graph is a straight line with negative slope passing through the origin.
