When given an equation or a table of data, often it is necessary to draw
a graphic representation to visualize and analyze the pattern.
|
The XYZ company is a new
company that manufactures school busses. The table below
displays how many busses the company built in the first four
days. If the company can keep producing busses at this
rate, complete the table and construct a line graph
representing the data. Let the x-axis represent the days
and the y-axis represent the number of busses produced. |
| Day |
1 |
2 |
3 |
4 |
5 |
6 |
7 |
| Total Built |
4 |
9 |
14 |
19 |
|
|
|
Let's take a look at the pattern...
Each day of production, the total built
is increasing by 5 busses. So... the table could be finished
like this...
| Day |
1 |
2 |
3 |
4 |
5 |
6 |
7 |
| Total Built |
4 |
9 |
14 |
19 |
24 |
29 |
34 |
Now we need to construct a line graph
using this data.
Can we now predict the number of busses
that will be produced on day 10? Absolutely!!! We can just
extend our table...
| Day |
8 |
9 |
10 |
| Total Built |
39 |
44 |
49 |
Let's look at another problem and
practice!
