Thaum nws los txog rau kev teeb tsa kev sib raug zoo tsis sib xws, nws yuav pab tau kom paub txog ob peb yam ntxwv ntawm kab zauv y=mx + b. Hauv kab zauv no, m yog sib npaug rau txoj kab nqes.

Yuav ua li cas yog qhov sib npaug ntawm kev sib raug zoo?

Linear equations tuaj yeem sau rau hauv daim ntawv y=mx + b. Thaum b ≠ 0, kev sib raug zoo ntawm x thiab y yog nonproportional.

Kev sib npaug ntawm kab yog dab tsi?

Kev sib npaug rau kev sib raug zoo yog y=2.8x. Yog hais tias kev sib raug zoo ntawm ob qhov ntau yog ib qho kev sib raug zoo, qhov kev sib raug zoo no tuaj yeem sawv cev los ntawm daim duab ntawm txoj kab ncaj nraim los ntawm lub hauv paus chiv keeb nrog txoj kab nqes sib npaug ntawm chav tsev.

Kab twg piav qhia txog kev sib raug zoo tsis sib xws?

Ib qho piv txwv yog ib txoj kab ncaj nraim uas ib txwm mus dhau qhov keeb kwm. Daim duab uas tsis muaj feem cuam tshuam yog kab ncaj nraim uas tsis mus dhau qhov keeb kwm.

Vim li cas ib qho kev sib npaug yuav raug txheeb xyuas tias tsis yog kev sib raug zoo?

Kev sib raug zoo tsis sib xws yuav cuam tshuam rau cov sawv cev no vim qhov y-intercept hauv daim duab yuav tsis yog xoom, qhov sib piv hauv cov lus yuav tsis sib npaug, thiab qhov sib npaug yuav raug cuam tshuam vim tus lej yuav muab ntxiv lossis rho tawm uas yog sawv cev los ntawm b.
