Siv daim ntawv nqes hav-intercept los nrhiav txoj kab nqes. Daim ntawv nqes hav-intercept yog y=mx + b y=m x + b, qhov twg m m yog txoj kab nqes thiab b b yog y-intercept. Siv daim ntawv nqes hav-intercept, txoj kab nqes yog Undefined. Tag nrho cov kab uas txuas mus rau m=47 m=4 7 muaj tib txoj kab nqes ntawm Undefined.
Dab tsi yog txoj kab nqes sib npaug rau M 3?
Algebra Piv txwv
Siv daim ntawv nqes hav-intercept, txoj kab nqes yog Undefined. Tag nrho cov kab uas txuas mus rau m=34 m=3 4 muaj tib txoj kab nqes ntawm Undefined.
txoj kab nqes nqes mus rau Y 4 yog dab tsi?
y=4 muaj slope=0. Nws yog ib txoj kab sib npaug mus rau x-axis hla tag nrho cov ntsiab lus uas y=4.
Yuav ua li cas koj pom txoj kab nqes nqes?
Ua ntej, koj yuav tsum muab qhov sib npaug rau nqes hav cuam tshuam daim ntawv (y=mx + b), qhov twg m yog txoj kab nqes. Txoj kab nqes ntawm txoj kab yog -3/8. Ib txoj kab sib txuas yuav muaj tib txoj kab nqes, yog li -3/8 yog cov lus teb raug.
Dab tsi yog parallel rau txoj kab nqes?
Ob kab yog parallel yog tias lawv muaj tib txoj kab nqes. Thaum saib tus qauv kab sib npaug, qhov tseem ceeb yog qhov 's yog tib yam. Nyob rau hauv cov ntaub ntawv no, tus kab zauv muab ib txoj kab nqes ntawm.
