1. find the gradient of each these lines
Penjelasan dengan langkah-langkah:
Rumus mencari gradien pada grafik
gradien = m
titik (a, b) dan (c, d)
m = (a – c)/(b – d)
atau
m = (c – a)/(d – b)
a) titik (2, 4) dan (4, 8)
m = (8-4)/(4-2) = 4/2 = 2
b) titik (8, 8) dan (1, 1)
m = (8-1)/(8-1) = 7/7 = 1
c) titik (3, 4) dan (2, 1)
m = (3-2)/(4-1) = ⅓
d) titik (8, 6) dan (2, 3)
m = (8-2)/(6-3) = 6/3 = 2
e) titik (5, 8) dan (4, 3)
m = (5-4)/(8-3) = 1/5
f) titik (-2, 8) dan (2, 0)
m = (-2-2)/(8-0) = –4/8 = –½
g) titik (4, 6) dan (5, 2)
m = (4-5)/(6-2) = –¼
h) titik (0, 6) dan (8, 2)
m = (0-8)/(6-2) = -8/4 = –2
i) titik (2, 6) dan (1, 0)
m = (2-1)/(6-0) = 1/6
