Answer
y = -2x - 1
Huu hapa ni utatuzi wa swali lako:
a) Andika mlinganyo wa mstari katika mfumo wa .
Step 1: Tambua gradient na y-intercept. Kutoka kwa swali, tunapewa gradient () ni na y-intercept () ni .
Step 2: Badilisha maadili haya kwenye fomula ya mlinganyo wa mstari. Fomula ya mlinganyo wa mstari ni . Mlinganyo wa mstari ni .
b) Tengeneza jedwali la maadili ukitumia angalau pointi tatu.
Step 1: Chagua maadili matatu ya . Tutatumia maadili ya kama ilivyo kwenye kazi yako.
Step 2: Tumia mlinganyo kupata maadili yanayolingana ya . • Kwa : • Kwa : • Kwa :
Jedwali la maadili ni:
c) Chora maadili yaliyotengenezwa ili kuchora mstari.
Step 1: Chora pointi kwenye grafu. Tumia jedwali la maadili kutoka sehemu (b) kuchora pointi zifuatazo kwenye grafu: • Pointi ya kwanza: • Pointi ya pili: • Pointi ya tatu:
Step 2: Unganisha pointi kwa kutumia mstari ulionyooka. Baada ya kuchora pointi zote tatu, chora mstari ulionyooka unaopita kwenye pointi hizo. Mstari huu unawakilisha mlinganyo .
Mchoro wako unaonyesha pointi zimechorwa kwa usahihi. Hatua inayofuata ni kuunganisha pointi hizo kwa mstari ulionyooka.
