Gambarlah grafik persamaan garis lurus berikut a. y = x - 2 b. -3y + 4x = 12 yg tau tolong jawab..tapi jangan asal ya..jawabannya difotoin kalo nggak d tls aja

A. y = x - 2 x = 0 ⇒ y = x - 2 y = 0 - 2 y = -2 titik (0, -2)
y = 0 ⇒ y = x - 2 0 = x - 2 2 = x titik (2, 0)
b. -3y + 4x = 12
x = 0 ⇒ -3y + 4x = 12 -3y + 4(0) = 12 -3y + 0 = 12 -3y = 12 y = 12/-3 y = -4 titik (0, -4)
y = 0 ⇒ -3y + 4x = 12 -3(0) + 4x = 12 0 + 4x = 12 4x = 12 x = 12/4 x = 3 titik (3, 0 )

Jawaban soal a garis y = x - 2 jika y = 1 maka x = ? y = x - 2 1 = x - 2 1 + 2 = x 3 = x titiknya (3,1) jika x = 1 maka y ? y = x - 2 y = 1 - 2 y = -1 titiknya ( 1,-1)
jawaban soal B -3y + 4x = 12 jika x = 0 maka y = ? -3y + 4x = 12 -3y +4(0) = 12 -3y + 0 = 12 -3y = 12 y = 12/-3 y = -4 jika y = 0 maka -3y + 4x = 12 -3(0) + 4y = 12 0 + 4y = 12 y = 12/4 y = 3
x = 0 ⇒ y = x - 2
y = 0 - 2
y = -2 titik (0, -2)
y = 0 ⇒ y = x - 2
0 = x - 2
2 = x titik (2, 0)
b. -3y + 4x = 12
x = 0 ⇒ -3y + 4x = 12
-3y + 4(0) = 12
-3y + 0 = 12
-3y = 12
y = 12/-3
y = -4 titik (0, -4)
y = 0 ⇒ -3y + 4x = 12
-3(0) + 4x = 12
0 + 4x = 12
4x = 12
x = 12/4
x = 3 titik (3, 0 )

garis y = x - 2
jika y = 1 maka x = ?
y = x - 2
1 = x - 2
1 + 2 = x
3 = x titiknya (3,1)
jika x = 1 maka y ?
y = x - 2
y = 1 - 2
y = -1 titiknya ( 1,-1)
jawaban soal B
-3y + 4x = 12
jika x = 0 maka y = ?
-3y + 4x = 12
-3y +4(0) = 12
-3y + 0 = 12
-3y = 12
y = 12/-3
y = -4
jika y = 0 maka
-3y + 4x = 12
-3(0) + 4y = 12
0 + 4y = 12
y = 12/4
y = 3
