### How to Plot/Graph/Show a system of linear equations

Disclaimer: I'm new to Sage Math and Linear equations.

Background: Google will plot/graph this search: "plot 3x+4y"

Questions:

In Sage Math, how can I show similar output as Google?

Is there a better way, in 2D or 3D, to plot the following? 3x+4y=2.5 AND 5x-4y=25.5 ?

.

`x, y = `~~var('x,y') ~~a=3*x+4*y==2.5

b=5*x-4*y==25.5

var('x,y')
a=3*x+4*y==2.5
b=5*x-4*y==25.5
p1=implicit_plot(a, (x,-2,5), (y,-4,4), axes="true", ~~aspect_ratio=1)~~

aspect_ratio=1)
p2=implicit_plot(b, (x,-2,5), (y,-4,4), axes="true", ~~aspect_ratio=1)~~

show(p1+p2)

aspect_ratio=1)
show(p1+p2)
