The slope of the Line is: -20
What is the Slope of the Line?
The slope of a line is defined as the ratio of the vertical and horizontal changes between two points on a surface or a line.
We see that the graph passes through the coordinates (2,80) and (4,40).
The formula for the slope of a line passing through two coordinates (x₁,y₁) and (x₂,y₂) is:
m = (y₂-y₁)/(x₂-x₁)
The points coordinates are:
(x₁,y₁) = (2,80) and (x₂, y₂) = (4,40)
Thus, the slope is:
m = (40 - 80)/(4 - 2)
m = -40/2
m = -20
