Given:
The table of values is:
x y
-4 3
0 8
4 13
8 18
To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{13-8}{4-0}[/tex]
[tex]m=\dfrac{5}{4}[/tex]
[tex]m=1.25[/tex]
Therefore, the slope of the line described by the data in the table is 1.25.
