Question

Find the slope of the line. 2 5 -9 The slope is

Answer 1

To calculate the slope of a line we need to find at least two points of the line.

For example, for this line, points (0,0) and (1,-3).

We can calculate the slope as:

`m=(y_2-y_1)/(x_2-x_1)=(-3-0)/(1-0)=(-3)/(1)=-3`

Answer: the slope is m=-3.
