Question
1.  "X is at most 3" can be represented by x ≤ 3. Is this true or  false?

2.  The sum of a number and -4 is greater than six.

Find the possible numbers.
n < 10
n > 10
n > 2
n < 2

3.  Find the solution set for -2y - 1 ≤ 7.
   y ≤ -3
   y ≥ -3
   y ≥ -4
   y ≤ -4

4.  Explain how you would graph the solution x ≤ 4.
