Penjelasan dengan langkah-langkah:
Ingat !
ax + bx + c = 0 ➡ m = -a/b
no. 1
m = -y/x
m = -(-2)/4
m = 2/4
m = 1/2
no. 2
• titik K(2, -3); x1 = 2 dan y1 = -3
• titik L(-2, 5); x2 = -2 dan y2 = 5
m = (y2 - y1)/(x2 - x1)
m = (5 + 3)/(-2 - 2)
m = 8/-4
m = -2
no. 3
(i) x - 2y = 5 ➡ m = -a/b = -1/-2 = 1/2
(ii) 2y = x + 7 ➡ m = 1/2
(iii) y + 2x - 3 = 0 ➡ m = -a/b = -2/1 = -2
Jadi, yang gradiennya 1/2 adalah i & ii
no. 4
3x + 2y = 0 ➡ m = -a/b = -3/2
Semoga Bermanfaat
