As an addition to the answer above, actually in Plots.jl it is even simpler. Just pass a function to plot like this:

plot(x->2x+5)

you typically will want to pass axis ranges which you can do like this:

plot(x->2x+5, xlim=(0,5), ylim=(5,15))

you can also plot several functions at once:

plot([sin, cos, x->x^2-1], label=["sin", "cos", "x²-1"], xlim=(-2,2), ylim=(-1,3))

The result of the last plotting command is: an example plot

Try looking at Julia's documentation about plotting as well as this tutorial found by searching Julia plots on a web search engine.

Plotting y = 2x+5 in Julia v1.1 :

using Pkg
Pkg.add("Plots") # Comment if you already added package Plots
using Plots
plotly() # Choose the Plotly.jl backend for web interactivity
x = -5:5 # Change for different xaxis range, you can for instance use : x = -5:10:5
y = [2*i + 5 for i in x]
plot(x, y, title="My Plot")
