Question

What is the slope of the line represented by the values in the table? x-10,2,3,7,20 and y-14,-2,0,8,34.

Answer 1

The slope of a line can be calculated as follows:

$\dfrac{y_{1}-y_{2} }{x_{1}-x_{2}}$

Plug in any two pairs of coordinates from the table, for instance:

$\dfrac{14-(-2) }{10-2}$

This simplifies to 2, therefore, the slope of the line is 2.
