Final answer:
Without the inequality provided, it's impossible to determine if the pairs are solutions. For the reference to linear equations, options A, B, and C are indeed linear because they can be represented as y = mx + b.
Step-by-step explanation:
To determine whether each ordered pair is a solution of the given inequality, we would typically substitute the x and y values from the ordered pair into the inequality and check to see if the inequality holds true. However, the inequality itself is not provided in your question, so I'm unable to test the ordered pairs (1, -2), (6, 0), (2, -1), and (-1, -1) directly.
If you can provide the inequality, I'd be happy to help you work through the problem.
As for your reference to Practice Test 4's question about linear equations, the answer is that all options A, B, and C are linear equations because they can be written in the form y = mx + b, where m and b are constants. This makes them straight lines with their respective slopes and y-intercepts.
Remember, a linear equation will always graph as a straight line, whether it has a positive slope, negative slope, or is a horizontal line (which occurs when the slope is zero).
