Question

What is the slope of line m?
On a coordinate plane, a straight line goes through (negative 2, 1), (0, 0), and (2, negative 1).

Answer 1

Given:

A straight line goes through (-2,1), (0,0), and (2,-1).

To find:

The slope of the given line.

Solution:

Slope formula

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

Consider any two points from the given points.

The line goes through (-2,1) and (0,0). So, the slope of the line is

$m=\dfrac{0-1}{0-(-2)}$

$m=\dfrac{-1}{2}$

Therefore, the slope of the line is $m=-\dfrac{1}{2}$.
