Answer:
y = -1/4x -10
Explanation:
Sides L and J are perpendicular to side K. Both have a "rise" of -1 for a "run" of 4, so a slope of -1/4. The only answer choice demonstrating a slope of -1/4 is the one shown above. It is the equation of the line containing side L, which intersects the y-axis at -10.
