What is the slope of a line that passes through the origin and the point (-2,1)?

Given:

A line passes through the origin and the point (-2,1).

To find:

The slope of the line.

Solution:

If a line passes though two point, then the slope of the line is

It is given that a line passes through the origin, .i.e., (0,0) and the point (-2,1). So, the slope of the line is

Therefore, the slope of the line is .
