kev sib raug zoo tsis sib xws tuaj yeem nthuav tawm hauv daim ntawv y=mx + b, qhov twg b tsis yog 0, m sawv cev rau qhov hloov pauv tsis tu ncua lossis nqes ntawm kab, thiab b sawv cev rau y-intercept. Daim duab ntawm kev sib raug zoo tsis sib xws yog txoj kab ncaj nraim uas tsis dhau los ntawm keeb kwm.
Kev sib raug zoo tsis muaj feem cuam tshuam yog dab tsi?
Daim duab ntawm kev sib raug zoo tsis sib xws yog kab uas tsis hla los ntawm lub hauv paus chiv keeb, whereas daim duab ntawm ib tug proportional linear kev sib raug zoo yog ib txoj kab uas hla mus txog. keeb kwm.
Qhov kev sib npaug twg sawv cev rau kev sib raug zoo tsis yog?
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.
Koj paub li cas yog tias kev sib raug zoo yog qhov sib npaug lossis tsis sib npaug?
Cov tub ntxhais kawm yuav tsum siv lawv txoj kev paub txog kev sib raug zoo thiab tsis sib luag los txiav txim siab thaum twg cov dej num yog proportional lossis tsis sib npaug. Proportional functions yuav nyob rau hauv daim ntawv y=kx thiab non-proportional functions yuav nyob rau hauv lub form y=mx + b.
Vim li cas daim duab no qhia txog kev sib raug zoo?
Daim duab yog proportional vim tus y rau x ratio yog tas li (tib yam). Daim duab tsis yog qhov sib npaug vim nws tsis dhau lub hauv paus chiv keeb (0,0). Daim duab yog proportional vim nws yog linear (ib txoj kab ncaj nraim). … Tsis sib npaug vim nws tsis dhau lub hauv paus chiv keeb (0, 0).
