I have two shapefiles that looks something like this:
One point file and one polyline file.
I want to find the points where the points and line would intersect if you drew a perpendicular line between them (the shortest distance). The next step is to mark these points on the polyline or a rasterized version of the polyline, but first I need to find a way to define them.
Because you have just two points and one line, so it's simple to implement what you need manually.
By start edit season on the line shapefile, create a feature (line).
start to draw line from the point 1 to the line (use right click>>prependicular). and draw another line from point 2 in the same way.
Then save and end the edit season.
If you would like to mark the result points, you can use (Add geometry attributes)
You can use also (Near tool) if you have advanced license.
