The following example shows how you can adjust the 

values manually (as opposed to using the standard 

values set by ( 

).

Yuko practices the piano 50 minutes per day. How many

minutes has he practiced after 2, 4, and 5 days? Graph your

answer.

1. A table of coordinate

pairs would look like

this:

X

 Y

2

100

4 200

5

250

2. A possible graph of the ordered pairs would look like this

(the 

 values are labeled):

³

Y=50X

X=number of days

Y=number of total minutes

The 

Y-axis is

measured in

increments of 50;

therefore, Yscl=50.

The 

X-axis is measured in increments

of 1; therefore, Xscl=1.
