The TI-Nspire Measurement Transfer tools allow you to transfer the result of a calculation, a numeric text value, or a measurement to a circle, ray, or vector. You can also use this tool to transfer a measurement to an axis. To transfer a slope measurement to the y-axis, follow these steps:

  1. Press [MENU]→Construction→Measurement Transfer to invoke the Measurement Transfer tool.

  2. Move the cursor to the result of the slope calculation (or numeric text value or measurement) and press [CLICK].

  3. Move the cursor to the y-axis and press [CLICK].

  4. Press [ESC] to exit the Measurement Transfer tool.

Notice that a point appears on the y-axis with a y-coordinate equal to the current value of the slope calculation. Try dragging the hollow point on the x-axis and watch as the point on the y-axis moves up and down.

Here are the results of using the Measurement Transfer tool. The y-axis is adjusted to provide a better window for seeing this result. The first two screens show the movement of the transferred measurement as the x-axis point is dragged. In the third screen, a perpendicular line is added through the transferred measurement and the intersection point, denoted (x,y), is constructed with the other perpendicular line.
