Question

Match the inequality with its graph.


1. x – 2y ≥ 6
2. x-2y > 4
3. y > 3+ ½ x
4. 4y +2y ≤ 1

Answer 1

\[y > 3+ ½ x\]
try to identify this one -- y must be greater than 3, always, and if x>0, then it must also be greater than the additional 1/2 x

the slope is positive, y is always higher than 3. which graph could that be?

Answer 2

would it be graph 55 then?

Answer 3

graph 55 looks similar, however, the slope in graph 55 is negative!

Answer 4

\[y > 3+ ½ x\]
1/2x is a positive slope, so the graph must go up

Answer 5

okay so then graph 58

Answer 6

graph 58 also has a negative slope, the line goes down
