plot 3.7*x+2.15 with lines linewidth 3 linecolor 1
The actual data is just randomly choosen points along the line, randomly displaced from it, created with a small Lua program:
function f (x) return 3.7 * x + 2.15 end
for _ = 1, 18 do
local x = math.random()
print(x, f(x) * (0.85 + 0.3 * math.random()))
end
