Align to Parallel
Adjust the slider to make the blue line parallel to the red line. Parallel lines have equal slopes.
Slope (m)
{{ state.s1.userM > 0 ? '+' : '' }}{{ state.s1.userM }}
Set to Perpendicular
Drag the blue point to make the line perpendicular to the red line. Their slopes must be negative reciprocals.

Find the Shortest Path
Drag the target along the red line to find the shortest distance to the blue point. The shortest path is perpendicular.
