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=3x+4y==2.5
b=5x-4y==25.5
p1=implicit_plot(a, (x,-2,5), (y,-4,4), axes="true", aspect_ratio=1)
p2=implicit_plot(b, (x,-2,5), (y,-4,4), axes="true", aspect_ratio=1)
show(p1+p2)
