Question Analysis
The main focus of this problem is to determine the slope of the altitude from point to the line . To do this, we first calculate the slope of line using the slope formula. Then, we use the property that the product of the slopes of two perpendicular lines is to find the slope of the altitude.
Key Concept Explanation
1. Slope formula: The slope of a line passing through two points and is given by .
2. Perpendicular lines: If two lines with slopes and are perpendicular, then . The altitude from a vertex of a triangle to the opposite side is perpendicular to that side.
