    y ≥ -4x - 2 C1) (4, 4) Put in the x-coordinate (-1) for x and put in the y-coordinate (0) for y. If the inequality is true, then it's a solution. Is 4 ≥ -4(4) - 2? 0 ≥ -16 - 2 0 ≥ -18 That statement is true, so (4, 4) is a solution. Do the same with the other ordered pairs in both problems.

    Can you follow my example above for choice C1? Try now cgoice A!, (-1, 0). Insert -1 for x and 0 for y, and see if it makes a true statement.

    (-4)(-1) = 4 When you multiply or divide numbers, two positives or two negatives make a positive. A negative and a positive make a negative.

    0 ≥ 4 - 2 0 ≥ 2 So it's A1?
