18

Step-by-step explanation:

All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's

Explanation:

If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.

Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.

You could also think of it like this:

Place point A at -12, B at 0, C at 6

The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.

Or you could use absolute value and subtraction

Let P = -12 and Q = 6

We could say

|P - Q| = |-12-6| = |-18| = 18

or

|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18

The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.
