5dregensleyerjawaban soal a y = 4x - 1 jika x = 0 maka y y = 4(0)-1 y = 0 -1 y = -1 melalui titik ( 0,-1) jika y = 0 maka x y = 4x - 1 0 = 4x -1 1 = 4x 1/4 = x melalui titik ( 1/4 , 0)
jawaban soal b 2x - 3y = 12 jika x = 0 maka y 2(0) - 3y = 12 -3y = 12 y = 12/-3 y = -4 melui titik (0,-4) jika y = 0 maka x 2x - 3y = 12 2x -3(0) = 12 2x = 12 x = 12/2 x = 6 melalui titik ( 6,0)
jawaban soal c x=2y - 2 jika x = 0 maka y 0 = 2y - 2 2 = 2y 2/2 = y 1 = y melui titik (0,1) jika y = 0 maka x x = 2y -2 x = 2(0) - 2 x = -2 melelui titik (-2,0)
jawaban soal D y = 4
jawaban soal E X = -1
jawaban soal F Y = X jika y = 0 maka x = 0 jika y = 1 maka x = 1 jika y = 2 maka x = 2
y = 4x - 1
jika x = 0 maka y
y = 4(0)-1
y = 0 -1
y = -1 melalui titik ( 0,-1)
jika y = 0 maka x
y = 4x - 1
0 = 4x -1
1 = 4x
1/4 = x melalui titik ( 1/4 , 0)
jawaban soal b
2x - 3y = 12
jika x = 0 maka y
2(0) - 3y = 12
-3y = 12
y = 12/-3
y = -4 melui titik (0,-4)
jika y = 0 maka x
2x - 3y = 12
2x -3(0) = 12
2x = 12
x = 12/2
x = 6 melalui titik ( 6,0)
jawaban soal c
x=2y - 2
jika x = 0 maka y
0 = 2y - 2
2 = 2y
2/2 = y
1 = y melui titik (0,1)
jika y = 0 maka x
x = 2y -2
x = 2(0) - 2
x = -2 melelui titik (-2,0)
jawaban soal D
y = 4
jawaban soal E
X = -1
jawaban soal F
Y = X
jika y = 0 maka x = 0
jika y = 1 maka x = 1
jika y = 2 maka x = 2
