Hello algebra classmates, here is my SeeLogo content. Enjoy!:

linestyle 0 2 [
local x1
x1 = -170 + RND 100
line purple x1 (-55) (30) (75)
line green (-82) (80) (20) (-60)
m1 = 130/(30-x1)
b1 = 75 - m1*30
m2 = -140/102
b2 = -3320/102
x= (b2 - b1)/(m1 - m2)
y = m1*x + b1
point orange x y

local x1
x1 = -170 + RND 100
line orange x1 (-120) (90) (76)
line blue (-170) (60) (100) (-70)
m1=196/(90-x1)
b1=76-m1*90
m2=-130/270
b2=60-m2*(-170)

x=(b2-b1)/(m1-m2)
y = m1*x+ b1
point green x y

x= (b2 - b1)/(m1 - m2)
y=m1*x + b1
