Find the slope of the line that passes through (2, 15) and (9, 10).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
In this case, the points are (2, 15) and (9, 10).
slope = (10 - 15) / (9 - 2)
= (-5) / (7)
= -5/7
Therefore, the slope of the line that passes through (2, 15) and (9, 10) is -5/7.
