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


m=(-1)/(2)

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