3.2-bo'lim : Chiziqlar

2. Quyidagi ikkita nuqtadan iborat chiziqning qiyaligini aniqlang va chiziqning grafigini chizing.

\[\left( {8,2} \right),\,\,\,\left( {14, - 7} \right)\]

Yechim

Keling, chiziqning qiyaligini topamiz. Biz yuqorida sanab o'tilgan birinchi nuqtani $\left( {{x_1},{y_1}} \right)$ nuqtasi va ikkinchi nuqtani qiyalik formulasida $\left( {{x_2},{y_2}} \right)$ nuqtasi bo'lishiga ruxsat beramiz. E'tibor bering, qaysi nuqta qaysi ekanligi muhim emas. Eng muhimi, qiymatlarni formulaga kiritganingizda izchil bo'lishingizdir.

Mana qiyalik.

\[m = \frac{{ - 7 - 2}}{{14 - 8}} = \frac{{ - 9}}{6} = - \frac{3}{2}\]

2-qadam

Mana chiziqning eskizi.

$The graph of the line through the two given points. It is a straight line falling from left to right and the points $\left( {8,2} \right)$ and $\left( {14, - 7} \right)$ are marked and labeled on it, along with the extra point $\left( {6,5} \right)$. A small dashed right triangle is drawn between $\left( {6,5} \right)$ and $\left( {8,2} \right)$ with the horizontal side labeled Run = 2 and the vertical side labeled Rise = -3 to illustrate the slope.$

Biz 1-bosqichda hisoblagan qiyalikni ko‘rsatish uchun qo‘shimcha nuqta, $\left( {6,5} \right)$ni qo‘shdik.
