1. **State the problem:** Solve the inequality $$2x - y \geq 1$$ graphically and find at least 6 ordered pairs that satisfy the inequality.
2. **Rewrite the inequality:** To graph the inequality, first express it in terms of $$y$$:
$$2x - y \geq 1 \implies -y \geq 1 - 2x \implies y \leq 2x - 1$$
3. **Graph the boundary line:** The boundary line is given by the equation:
$$y = 2x - 1$$
This is a straight line with slope 2 and y-intercept -1.
4. **Plot the boundary line:**
- When $$x=0$$, $$y = 2(0) - 1 = -1$$, so point (0, -1).
- When $$x=1$$, $$y = 2(1) - 1 = 1$$, so point (1, 1).
5. **Determine the inequality region:** Since the inequality is $$y \leq 2x - 1$$, the solution region is the area **below or on** the line.
6. **Check a test point:** Use point (0,0):
$$0 \leq 2(0) - 1 = -1$$ is false, so (0,0) is **not** in the solution region.
7. **Find 6 ordered pairs satisfying $$y \leq 2x - 1$$:** Choose values of $$x$$ and calculate $$y$$ such that $$y \leq 2x - 1$$:
- For $$x=0$$, $$y \leq -1$$, e.g., (0, -1), (0, -2)
- For $$x=1$$, $$y \leq 1$$, e.g., (1, 1), (1, 0)
- For $$x=2$$, $$y \leq 3$$, e.g., (2, 3), (2, 2)
**Six ordered pairs:** (0, -1), (0, -2), (1, 1), (1, 0), (2, 3), (2, 2)
**Final answer:** The inequality $$2x - y \geq 1$$ is equivalent to $$y \leq 2x - 1$$. The graph is the line $$y = 2x - 1$$ with the solution region below or on this line. Six points satisfying the inequality are (0, -1), (0, -2), (1, 1), (1, 0), (2, 3), and (2, 2).
