y = Gleichung
y1 = y1-Koordinate
y2 = y2-Koordinate
x1 = x1-Koordinate
x2 = x2-Koordinate
y2 = y2-Koordinate
y1 = y1-Koordinate
y2 = y2-Koordinate
x1 = x1-Koordinate
x2 = x2-Koordinate
x2 = x2-Koordinate

\( y = m \times x + \left( y_2 - m \times x_2 \right) \)
y = Gleichung
m = Steigung
y2 = y2-Koordinate
m = Steigung
x2 = x2-Koordinate

\( y = m \times x + \left( y_1 - m \times x_1 \right) \)
y = Gleichung
m = Steigung
y1 = y1-Koordinate
m = Steigung
x1 = x1-Koordinate

Zwei Punkte Form
