M'buku lino, tiwona zomwe zimadutsa mizere iwiri, ndi momwe tingapezere makonzedwe ake m'njira zosiyanasiyana. Tidzasanthulanso chitsanzo cha kuthetsa vuto pamutuwu.
Kupeza zolumikizira za podutsana
mphambano Mizere yomwe ili ndi mfundo imodzi yofanana imatchedwa.
M ndiye podutsa mizere. Ndi ya onse awiri, zomwe zikutanthauza kuti ma coordinates ake amayenera kukhutitsa ma equation awo nthawi imodzi.
Kuti mupeze makonzedwe a mfundoyi pa ndege, mungagwiritse ntchito njira ziwiri:
- likutipatsa - Jambulani ma graph a mizere yowongoka pa ndege yolumikizirana ndikupeza malo awo olowera (osagwira ntchito nthawi zonse);
- kulingalira ndi njira wamba. Timagwirizanitsa ma equation a mizere mu dongosolo. Kenako timachithetsa ndikupeza zolumikizira zofunika. Momwe mizereyo imakhalira polemekezana wina ndi mzake zimatengera kuchuluka kwa mayankho:
- njira imodzi - kudutsa;
- njira zothetsera ndizofanana;
- palibe mayankho - kufanana, mwachitsanzo, osadutsana.
Chitsanzo cha vuto
Pezani zolumikizira za podutsa mizere
Anakonza
Tiyeni tipange dongosolo la ma equation ndikuthetsa:
Mu equation yoyamba, timafotokozera x kudzera y:
x = y-6
Tsopano tikulowetsa mawu otulukawo mu equation yachiwiri m'malo mwa x:
y = 2 (y – 6) – 8
y = 2y - 12 - 8
y - 2y = -12 - 8
-y = -20
y = 20 ndi
Choncho, x = 20 – 6 = 14
Chifukwa chake, nsonga yodziwika bwino yodutsa mizere yoperekedwayo ili ndi zolumikizira
