What this problem tests

Tests the ability to convert a linear equation to slope-intercept form, apply the perpendicular slope condition, and solve for the y-intercept using a given point.

This is a fundamental problem in coordinate geometry, often encountered in precalculus and early calculus courses as a prerequisite skill.
