Choose the correct solution and graph for the inequality.

Question

z + 9 less than or equal to 6

Answer 1

The correct solution is z ≤ -3.

To graph this inequality, we first draw a number line and plot a solid dot on -3 to indicate that it is included in the solution. Then, we shade the portion of the number line to the left of -3 to represent all the numbers that are less than or equal to -3.
