Answer:
m = -3/2
Explanation:
Given the following points on the graph, (0, 9) and (2, 6):
Let (x₁, y₁) = (0, 9)
(x₂, y₂) = (2, 6)
Plug these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 9)/ (2 - 0)
m = -3/2
Therefore, the slope of the graph is -3/2. It has a negative value (hence, a negative slope) because the line is declining from the left side of the graph towards the right.
