The slope of the line is zero beacuse it is a straight line.
What is the slope?
The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line is calculated as follows:
m = Δy/Δx
Given that the line that passes through the points (-1, -2) and (3, -2)
To find the slope of the line that passes through points (-1, -2) and (3, -2)
Therefore, the slope of the line is;
m = Δy/Δx
m = (-2 + 2)/(3 - 1)
m = 0
Hence, the slope of the line is zero beacuse it is a straight line.
