Answer:

  1 : 6

Step-by-step explanation:

The given scale factor is ...

  2 in : 1 ft

To express this as a ratio of pure numbers (without units), the units must be the same on either side of the colon (:). Here, we can make that happen by changing 1 ft to its equal in inches: 12 inches.

  2 in : 1 ft = 2 in : 12 in = 2 : 12 = 1 : 6

We generally like to have the scale factor reduced to lowest terms, so we want to remove any common factors from the numbers.

The scale factor of 2 in to 1 foot is 1 : 6.

Answer:

-6/8

Step-by-step explanation:

The rate of change is the same as the slope (I don't know if you have learned that term yet), but basically its the change in y's over the change in x's. to find this out, all you have to do is count from the point on the graph that is the farthest right (in this case, (6,1)), up to the y coordinate of the point farthest to the left (-2, 7) which is 6, and then count the number of spaces between the x coordinates, which is 8. put the rise (up and down count) over the run (horizontal count) in a fraction form, which gives you 6/8, and then notice how the line is pointing towards the bottom RIGHT hand corner making the line negative, so you need to make the rate of change negative, giving you the final answer of -6/8.
