CPM Homework Help : CC2 Problem 2-115

Complete the scaling for each number line or set of axes.

Step 1 (a):
Determine the size of each interval.
$\frac{64-32}{4}=\frac{32}{4}=8$
Step 2 (a):
Add to or subtract from the numbers on the given points in order to fill in the missing numbers.

Hint (b):
Follow the steps given for part (a).
More Help (b):
The intervals have a width of $0.25$ or $\frac{1}{4}$ .

Hint (c & d):
Remember that the point where the axes intersect is $0$ on both axes.
More Help (c & d):
Fill in each axis as you did the two number lines above. Remember that the two axes may have different scaling.

Answer (d):

First quadrant graph, x axis with 5, equally spaced, marks, labeled as follows: 4, 8, 12, 16, 20. y axis with 3, equally spaced, marks, labeled, 4, 8, 12.
