Example translating points
Khan Academy・2 minutes read
The video explains how to perform point translations on a coordinate plane, demonstrating the algebraic method of reducing the x-coordinate by a certain value and increasing the y-coordinate by another value. This method is applied to a point with coordinates (3, -4), resulting in new coordinates of (-2, -1) after the translation.
Insights
- The video demonstrates the algebraic method of describing point translations on a coordinate plane, showcasing a systematic approach where x-coordinates are decreased and y-coordinates are increased by specified units.
- Through the example of translating a point with coordinates (3, -4) by five units to the left and three units up, the algebraic formula (-5, +3) effectively transforms the original point to (-2, -1), illustrating a clear connection between the algebraic rules and the resulting coordinates.
