为什么当我试图绘制图形时,这段代码不起作用?y截距似乎不起作用。
from turtle import *
m = float(input("What is the slope? "))
b = float(input("What is the y-intercept? "))
x= window_width()
y= window_height()
y= int(m*x + b)
pd()
goto(x , y)
pd()
goto(-x,-y)
pu()
goto(x/2,0)
pd()
goto(-x/2,0)
pu()
goto(0,2*y)
pd()
goto(0,-2*y)
update()
当我用y截取测试值时,它们会穿过原点,这意味着它不起作用。我在试着让y-截距工作。
