According to the class materials, the number of edges in km,n is the product of m and n (mn). 1. (a) true 2. (b) false

Step-by-step explanation:

Given is an inequality that

To find the number line that represents the above inequality

First we must solve the inequality with positive x on one side

Given inequality is

To solve for x we must get x on left side

Hence divide by -1.  Since when we divide/multiply by a negative number inequality gets reversed we get

is the solution.

i.e. the number line representing the region to the left of -4 including the value of -4
