What is the slope of the line that passes through the points (-2,5) and (1,4)?
A. -3
B. -2
C. -1/3
D. 1/3
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
Applying the formula to the given points:
slope = (4 - 5) / (1 - (-2))
= -1 / 3
The slope of the line passing through the points (-2,5) and (1,4) is -1/3.
Therefore, the answer is C. 1/3.
