Question

Kerjain semuanya pakai cara dong..pliss bantuu:(

Answer 1

1. titik potong di sumbu Y (nilai x = 0)
a) m = 5, titik potong (0, 3)
y = 5 × 0 + 3
y = 3

b) m = 1/2, titik potong (0, -6)
y = 1/2 × 0 - 6
y = -6

c) m = 4, titik potong (0, 0)
y = 4 × 0
y = 0

d) m = -3, titik potong (0, 4)
y = -3 × 0 + 4
y = 4

e) m = -4_1/2, titik potong (0, -2)
y = -4_1/2 × 0 - 2
y = -2

f) m = 0, titik potong (0, -5)

2. m = 2
a) y - 5 = 2 × (x - 0)
y - 5 = 2x
2x - y + 5 = 0

b) y - (-3) = 2 × (x - 0)
y + 3 = 2x
2x - y - 3 = 0

c) y - 2_1/2 = 2 × (x - 0)
y - 5/2 = 2x
2y - 5 = 4x
4x - 2y + 5 = 0

d) y - 0 = 2 × (x - 0)
y = 2x
2x - y = 0

3. Titik (0, -6)
a) y - (-6) = 4 × (x - 0)
y + 6 = 4x
4x - y - 6 = 0

b) y - (-6) = 1/2 × (x - 0)
y + 6 = 1/2 x
2y + 12 = x
x - 2y - 12 = 0

c) y - (-6) = 2/3 × (x - 0)
y + 6 = 2/3 x
3y + 18 = 2x
2x - 3y - 18 = 0

d) y - (-6) = 0 × (x - 0)
y + 6 = 0
