Umeuliza kuhusu kuchora grafu ya mlinganyo nilioupata hapo juu, ambao ni y=−x+2y = -x + 2. Hapa kuna hatua za kuchora grafu hiyo:

  1. Tambua kizuizi cha y (y-intercept).

    Katika mlinganyo y=−x+2y = -x + 2, kizuizi cha y ni c=2c = 2. Hii inamaanisha mstari unakata mhimili wa y kwenye pointi (0,2)(0, 2).

  2. Tambua mteremko (slope).

    Mteremko wa mlinganyo y=−x+2y = -x + 2 ni m=−1m = -1. Hii inaweza kuandikwa kama −11\frac{-1}{1}. Mteremko wa −11\frac{-1}{1} unamaanisha kuwa kwa kila hatua 1 unayosonga kulia kwenye mhimili wa x, mstari unashuka hatua 1 chini kwenye mhimili wa y.

  3. Chora kizuizi cha y.

    Weka alama kwenye pointi $(0, 2)$ kwenye ndege ya kuratibu (coordinate plane).

  4. Tumia mteremko kupata pointi nyingine.

    Kuanzia kwenye kizuizi cha y (0,2)(0, 2), songa hatua 1 kulia (hadi x=1x=1) na hatua 1 chini (hadi y=1y=1). Hii inakupa pointi (1,1)(1, 1).
    Unaweza pia kusonga hatua 2 kulia (hadi x=2x=2) na hatua 2 chini (hadi y=0y=0). Hii inakupa pointi (2,0)(2, 0), ambayo pia ni kizuizi cha x (x-intercept).

  5. Chora mstari.

    Chora mstari ulionyooka unaounganisha pointi ulizoweka alama.

    Grafu itakuwa mstari unaopita kwenye pointi $(0, 2)$ na $(2, 0)$.
