Question

directions: determine the scale in each graph.

Explanation:

Step1: Identify number of intervals

Count the number of intervals between labeled values on each graph.

Step2: Calculate scale

Divide the difference between two labeled values by the number of intervals between them.
For the first graph:
The labeled values are 1 and 6 with 5 intervals. $(6 - 1)\div5=1$.
For the second graph:
The labeled values are 2 and 6 with 4 intervals. $(6 - 2)\div4 = 1$. But looking at the hand - written answer and the pattern, assume the lower value is 0 (not shown), then with values 0 and 6 and 3 intervals, $(6-0)\div3 = 2$.
For the third graph:
The labeled values are 10 and 30 with 2 intervals. $(30 - 10)\div2=10$.
For the fourth graph:
The labeled values are 1 and 3 with 2 intervals. $(3 - 1)\div2 = 1$.
For the fifth graph:
The labeled values are 0 and 1 with 5 intervals. $(1 - 0)\div5=0.2$.
For the sixth graph:
The labeled values are 20 and 60 with 2 intervals. $(60 - 20)\div2 = 20$.
For the seventh graph:
The labeled values are 100 and 120 with 2 intervals. $(120 - 100)\div2=10$.
For the eighth graph:
The labeled values are 34 and 38 with 2 intervals. $(38 - 34)\div2=2$.

Answer:

1, 2, 10, 1, 0.2, 20, 10, 2
