Question

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

Answer 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

`m=(y_2-y_1)/(x_2-x_1)`

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

`m=(1-0)/(-2-0)`

`m=(1)/(-2)`

`m=-(1)/(2)`

Therefore, the slope of the line is
`-(1)/(2)`.
