Test tag: <tc>#is#Line.__init__</tc> Test tag: <tc>#tests#Line.__init__</tc>

Parameters

mthe slope of the line

bthe y-intercept of the line

>>> ls = Line(1, 0)
>>> ls.m
1.0
>>> ls.b
0.0

Methods

__init__(self, m, b)	Returns a Line object.
x(self, y)	Returns the x-value of the line at a particular y-value.
y(self, x)	Returns the y-value of the line at a particular x-value.

x(self, y)

Returns the x-value of the line at a particular y-value.

x(number) -> number

Parameters

ythe y-value to compute x at

Examples

>>> l = Line(0.5, 0)
>>> l.x(0.25)
0.5

y(self, x)

Returns the y-value of the line at a particular x-value.

y(number) -> number

Parameters

xthe x-value to compute y at

Examples

>>> l = Line(1, 0)
>>> l.y(1)
1.0
