Question: Plot of equation of secant line

I using Maple 18.

I write below procedure,

local y,x;



end proc:

when I use Eqplot(2,3) , then I will expect the result for both of equation 2x+3 and sketch y=2x+3, but unfortunately the result is only sketch y=2x+3.

please hint me about that how I can write a proc that result be both of 2x+3 and sketch 2x+3 in maple 18?
