tentukan gradien 1. y=1/3x+5 2. 3y =6x+9 3. 7y-4x+28=0 4. 5x + 6y =30

Materi : Persamaan Garis
Kelas : VIII SMP

1 . [][][]
y = 1/3 x + 5

m = 1/3

2 . [][][]
3y = 6x + 9
y = 6/3 x + 9/3
y = 2x + 3

m = 2

3 . [][][]
7y - 4x + 28 = 0
7y = 4x - 28
y = 4/7 x - 28/7
y = 4/7 x - 4

m = 4/7

4 . [][][]
5x + 6y = 30
6y = -5x + 30
y = -5/6 x + 30/6
y = -5/6 x + 5

m = -5/6

1. m = 1/3
2. 3y = 6x + 9
(dibagi 3 semua biar y hasilnya 1)
y = 2x + 3
m = 2
3. m = -a/b
m = -7/4
4. itu nomor 4 btw belakangnya beneran 30?
