Txij li thaum a taw tes ntawm kev sib tshuam yog nyob rau ntawm ob kab, nws yuav tsum yog ib qho kev daws rau ob qho tib si sib npaug. 5. Joel hais tias a qhov system ntawm kab tawm kev sib npaug yeej yuav muaj raws nraim ib daws thaum twg qhov nqes hav ntawm ob kab yog txawv. Yog li ntawd, lawv yuav tsum sib tshuam ntawm ib thiab xwb ib point.
Xav txog qhov no, puas tuaj yeem muaj ntau tshaj ib qho kev sib tshuam?
Kev piav qhia: Yog tias koj muaj qhov chaw sib txawv ntawm ib point cov kab yuav hla ib leeg vim lawv tsis parallel. Yog li ntawd rau lawv ua ntau lub ntsiab lus ntawm kev sib tshuam tsis tsuas yog txoj kab nqes yuav tsum zoo ib yam nkaus tab sis y-intercept yuav tsum zoo li.
puas tuaj yeem muaj ntau tshaj ib qho kev sib tshuam ntawm cov duab ntawm ob kab zauv piav qhia? Tsuas yog cov graphs ntawm ob kab zauv sib npaug sib ntsib, muaj tau ua xwb ib qho kev sib tshuam , vim ob kab tuaj yeem sib tshuam hauv feem ntau ib point.
Yog li ntawd, muaj pes tsawg txoj kev daws teeb meem thaum cov kab sib tshuam hauv ib qho taw tes?
Cov kab sib tshuam ntawm ib qho chaw ,so ob kab muaj tsuas yog ib qho xwb zoo sib xws. Nyob ntawd yog tsuas yog ib qho kev daws teeb meem xwb mus rau qhov system. Vim lub kab tsis zoo ib yam, qhov sib npaug yog ywj siab. Vim nyob ntawd yog tsuas yog ib qho kev daws teeb meem xwb , qhov system no zoo ib yam.
Koj pom cov ntsiab lus ntawm kev sib tshuam li cas?
Yuav nrhiav tau taw tes ntawm kev sib tshuam algebraically, daws txhua qhov sib npaug rau y, teeb tsa ob kab lus rau y sib npaug rau ib leeg, daws rau x, thiab ntsaws tus nqi ntawm x rau hauv ib qho ntawm qhov sib npaug qub kom pom qhov sib thooj y-tus nqi. Cov nqi ntawm x thiab y yog cov x- thiab y-tus nqi ntawm cov taw tes ntawm kev sib tshuam.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas muaj ntau tshaj ib qho kev sib tshuam ntawm cov duab ntawm ob kab sib npaug?
Tshwj tsis yog cov duab ntawm ob kab sib npaug sib npaug sib npaug, tsuas muaj ib qho kev sib tshuam xwb, vim tias ob kab tuaj yeem sib tshuam hauv feem ntau ntawm ib qho. Los ntawm qhov ntawd, txav ib chav mus rau sab xis thiab txav mus rau vertically tus nqi ntawm txoj kab nqes mus rau qhov chaw thib ob. Tom qab ntawd txuas ob lub ntsiab lus
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem.
