- The key here is knowing what is meant by an ordered pair. The numbers in ( ) are the values for x and y, namely (x,y) so let's explore this one: y < = 1/2 x + 3 # 1 (-8,-10) --> that would mean -10 < = 1/2 (-8) + 3 -10 < = -4 + 3 -10 < = -1 is -10 < = -1 ? YES so that automatically eliminates choices B and C # 2 (-2, 2) -- > -2 < 1/2 (2) + 3 -2 < 1 + 3 -2 < 4 YES that eliminates E # 3 (14,4) --> 14 < 2(4) + 3 14 < 8 + 3 14 < 11 NO that eliminates A the only one left is choice D - 1 and 2 Hope that helps
- tiero416, you seem to have four errors. You switched X and Y when checking the points (-2,2) and (14,4). You also neglected to use <= (instead of <). I believe all three points satisfy the inequality. So the answer is "1,2&3".
