Question

What is the slope of the line described by the data in the table below?

Answer 1

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

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{13-8}{4-0}$

$m=\dfrac{5}{4}$

$m=1.25$

Therefore, the slope of the line described by the data in the table is 1.25.
