Pronunciation: /skeɪl/ Explain
The scale of a
states the interval
by tic marks on the graph.
In the number line in figure 1, the scale is 1. This is because each tic mark to the right
represents one more than the previous tic mark.
Figure 1: Number line from -10 to 10 by ones.
The scale for the number line in figure 2 is 1/10 because
the value of the tic marks increase by 1/10 for each tic mark to the right.
Figure 2: Number line from -1 to 1 by tenths.
To scale a geometric figure is to change the size of
the figure without changing any other features. In pure mathematics, this is called
The scale factor
is called the dilation ratio.
