I expect that plot? will tell you -- as I don't know without looking
myself, I wil let you look!

Thanks for reply, Can you tell me how should I change the ratio?

For both graphs you have set the x-range to -10..10 but the y-ranges are
different, and the graph has been scaled so that (as you can see from the
axes) the aspect ratio is not 1:1.
Try specifying equal y-ranges as well as equal x-ranges.

Suppose we have two equations
p1 = 3x+ 1
p2 = -1/3x + 3
As you may know because of slopes, these two lines must be perpendicular.
It's true when I plot it on paper but when I do it in SageMath I get this:
sage: p1 = plot( 3*x + 1, -10, 10)
sage: p2 = plot( -1/3*x + 3, -10, 10)
sage: show ( p1 +
