Question

Translate (2,1) to the left 1 unit

Answer 1

To translate the point (2,1) to the left by 1 unit in the Cartesian coordinate system, subtract 1 from the x-coordinate to get the new coordinates (1,1).

Step-by-step explanation:

The student has asked how to translate the point (2,1) to the left by 1 unit. In the Cartesian coordinate system, moving a point to the left by 1 unit involves subtracting 1 from the x-coordinate while keeping the y-coordinate the same.

Here’s how you do it step by step:

1. Start with the original coordinates of the point, which are (2,1).
2. To translate to the left by 1 unit, subtract 1 from the x-coordinate (which is 2) and keep the y-coordinate (which is 1) unchanged.
3. The new coordinates after the translation will be (2 - 1, 1), which simplifies to (1,1).

Therefore, the point (2,1) translated to the left 1 unit will have the coordinates (1,1).
