I think you already found the actual perpendicular line. You just thought you haven't because a plot with aspect ratio $\neq 1$ misled you.. If you try Plot[y[x],{x,0,5},Prolog->{PointSize[.02],Through[{Point,Line}[{{4,3},{x,y[x]}/.x->3.85977}]]},AspectRatio->Automatic], you'll see what I mean.

| Jun 10, 2013 at 17:31 | comment | added | Daniel Lichtblau | What @Silvia is saying is that the line through that point (probably) is perpendicular, and simply does not look so. This happens because aspect ratio !=1 will distort scale. | |
| Jun 10, 2013 at 17:16 | comment | added | Raymond Ghaffarian Shirazi | actually no it's not silvia. it's about finding actual perpendicular line I don't really care about aspect ratio. as I mentioned in the title. | |

| Jun 10, 2013 at 16:48 | comment | added | Silvia | I voted to close as I think your real question is merely about plot with specific aspect ratio, which in my opinion is a please-read-the-documentation question and too localized (also might be duplicate). | |
| Jun 10, 2013 at 16:36 | comment | added | Silvia | Have you tried the option I mentioned above? Does it look right with that option? | |
| Jun 10, 2013 at 16:31 | comment | added | Raymond Ghaffarian Shirazi | yes the plot doesn't look perpendicular to me if you know how you can plot it better please let me know too | |
| Jun 10, 2013 at 16:11 | comment | added | Silvia |
I'm not following you. It looks to me the right answer indeed. Or do you mean the plot looks not perpendicular? Have you tried Plot with option AspectRatio -> Automatic?
