Discovering a Formula for the Slope of a Line (WS 7)
Below you can see a line and its corresponding linear
Note: Write down all your answers on a sheet of paper.
- Find a way to calculate the slope m of the
(a) Use the coordinates of points X1
to calculate the side lengths of the
slope triangle. Write down your assumption.
(b) Check your assumption for at least 3 different positions of the
well as for 2 different values of slider m.
- Write down your formula for the slope m in a
abstract way. Use the general coordinates X1 = (x1,
y1) and X2 = (x2,
y2) in your formula.
