1. Persamaan garis berikut yang melalui titik (7,4)

Jawab:

c. 2x – 5y = -6

Penjelasan dengan langkah-langkah:

a.

y = 2(7) – 6

y = 14 – 6 = 8

b.

x – 6y = 5

x = 5 + 6(4)

x = 5 + 24 = 29

c.

2x – 5y = -6

2x = -6 + 5(4)

2x = -6 + 20

2x = 14

x = 7

d.

3x + 5y = 6

3x = 6 – 5(4)

3x = 6 – 20

3x = -14

x = -4
