Answer:

The scale factor should be 1:2 cause from 2.1 to 4.2 is doubled and so is 7.5 to 15 and 5.5 to 11.

Answer:

  see attached for the drawing

  slope = -1/2

Step-by-step explanation:

For the rise of -1 and the run of 2, the slope is ...

  m = rise/run = -1/2 . . . . slope in simplest form

<em>Additional comments</em>

It usually works best if you can identify points on the graph where the line crosses grid intersections. Then the number of squares in each direction can be counted easily. If you work with two grid intersections that are closest together, then the ratio of rise to run will already be in reduced form.

On this graph, there are other grid crossing points that are 4, 6, 8 units to the right or left of the one where we started. You need to remember that "run" is positive in the "right" direction, and "rise" is positive in the "up" direction.

We have shown the "rise" and "run" lines above the graphed line. They can also be shown below the graphed line.

Here, the grid squares are 1 unit in each direction. You need to pay attention to the scale, because some graphs have different numbering vertically than horizontally. The values for "rise" and "run" need to be figured using the appropriate scale.

How can I use the Distributive Property to answer 144 -:- 8??
MAXImum [283]

Distributive property of division is that the division of a sum equals the division of the summands.
Algebraically, this is:
[x + y + z] / a = x/a + y/a + z/a.
So, applying this to 144 / 8, you can split 144 as [72 + 32 + 40] / 8 = 72/8 + 32/8 + 40/8 = 9 + 4 + 5 = 18
