y = 4 y = -3 etc. Replace the number to the right with any convenient number. For example, in the first equation, the line is 4 units above the x-axis.
3.5 units, or 3 units (to be pedantic).
3 X 3 X 2 = 18 cubic units.
A number line can help you visualize this. See http://en.wikipedia.org/wiki/Number_line for an example, and a description. On a number line, adding 3 means to go 3 units to the right; if you start at -9 and go 3 units to the right, you end at -6, 'tis as simple as that. (Subtracing a number means going a certain number of units to the left.)

The origin, O is the point where the value on the number line is zero. Locate the a point 3 units to the left of the Origin, O and another point that is 5 units to the right of the origin. Join the two points with a straight line.

If you start at 0 then: 0+5-3+4=6 I hope it helped you

Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
This is the fraction or number representing how many units up a line goes for ever unit it goes laterally. For example, a slope of 2/3. This line goes up two units for every three it goes sideways.
Sample Response: Plot –3 on a number line. Find the distance the point is from 0. –3 is 3 units from zero. The absolute value is the distance from 0. The absolute value of –3 is 3.
