Question Analysis
The main focus of this question is to determine the slope of the altitude from point to the line . We first need to calculate the slope of the line using the slope formula for two points. Then, we will 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 are perpendicular, and their slopes are and respectively, then . The altitude from a vertex of a triangle to the opposite side is perpendicular to that side.
Step - by - Step Solution
1. Find the slope of line :
Given and , substitute , , , and into the slope formula.
