Dab tsi yog abscissa ntawm point (- 3 4?
ABSCISSA LUB POINT (-3. 4) YOG (-3). Raws li ABSCISSA yog tus nqi ntawm X-axis thiab hauv qhov no X-axis yog -3.
Dab tsi yog abscissa ntawm (- 3 5?
Teb: abscissa ntawm point (3, -5) yog 3. abscissa yog x-coordinate thaum ordinate yog y coordinate.
Koj txhais li cas los ntawm abscissa thiab ordinate of a point?
Abscissa yog qhov kev ncua deb ntawm qhov taw tes mus rau ntsug lossis y -axis, ntsuas qhov sib npaug mus rau kab rov tav lossis x -axis. Nws tseem hu ua x-coordinate. Ordinate yog qhov kev ncua deb ntawm qhov taw tes mus rau kab rov tav lossis x -axis, ntsuas thaum uas tig mus rau ntsug lossis y -axis.
