Nov yog qee cov kauj ruam ua raws li:

  1. Plug x = 0 to kev sib npaug thiab daws y.
  2. Teeb lub point (0, y) ntawm y-axis.
  3. Plug y = 0 rau hauv kev sib npaug thiab daws x.
  4. Npaj lub point (x, 0) ntawm x-axis.
  5. Kos ib txoj kab ncaj nraim ntawm ob lub ntsiab lus.

Ib yam li ntawd, koj tuaj yeem nug, koj yuav ua li cas daws qhov kev sib npaug ntawm cov duab ib kauj ruam?

Cov kauj ruam

  1. Xyuas kom tseeb tias cov kab zauv sib npaug yog nyob rau hauv daim ntawv y = mx + b.
  2. Npaj tus lej b ntawm Y-axis.
  3. Hloov m rau hauv ib feem.
  4. Pib ncua txoj kab los ntawm b siv txoj kab nqes, lossis nce hla kev khiav.
  5. Txuas ntxiv rau txoj kab, siv tus pas ntsuas thiab nco ntsoov siv txoj kab nqes, m, raws li kev qhia.

Tsis tas li ntawd, koj ua li cas kos ib kab los ntawm kev sib npaug? Txhawm rau kos ib kab zauv sib npaug, peb tuaj yeem siv txoj kab nqes thiab y-intercept.

  1. Nrhiav qhov y-intercept ntawm daim duab thiab npaj lub ntsiab lus.
  2. Txij ntawm no mus, siv txoj kab nqes los nrhiav qhov thib ob thiab teeb tsa nws.
  3. Kos cov kab uas txuas ob lub ntsiab lus.

Kuj tseem paub yog, koj ua qhov sib npaug ntawm daim duab li cas?

Rau sau ib kev sib npaug nyob rau hauv daim ntawv nqes hav-intercept, muab a daim duab ntawm qhov ntawd kev sib npaug , xaiv ob lub ntsiab lus ntawm kab thiab siv lawv los nrhiav txoj kab nqes. Qhov no yog tus nqi ntawm m nyob rau hauv lub kev sib npaug . Tom ntej no, nrhiav cov kev tswj hwm ntawm y-intercept--qhov no yuav tsum yog ntawm daim ntawv (0, b). Tus y-coordinate yog tus nqi ntawm b nyob rau hauv lub kev sib npaug.

Yuav ua li cas koj nrhiav tau qhov system ntawm equations?

Nov yog qhov nws mus:

  1. Kauj Ruam 1: Daws ib qho kev sib npaug rau ib qho ntawm qhov sib txawv.
  2. Kauj Ruam 2: Hloov qhov sib npaug mus rau lwm qhov sib npaug, thiab daws rau x.
  3. Kauj Ruam 3: Hloov x = 4 x = 4 x = 4 rau hauv ib qho ntawm qhov sib npaug qub, thiab daws rau y.
