SMP Kelas VIII
y = mx + c
m = gradien
y = 4x - 1
m = 4
Sejajar, maka m₁ = m₂ = 4
melalui titik (-2, 5)
(y - y₁) = m(x - x₁)
(y - 5) = 4(x -(-2))
(y - 5) = 4(x + 2)
y - 5 = 4x + 8
y = 4x + 8 + 5
y = 4x + 13
m= 4
= y - y1 = m ( x - x1 )
= y- 5 = 4 ( x - (-2)
= -5y. = 4 ( x + 2)
= -5y = 4x + 8
= y. = 4x + 8 + 5
=. y = 4x + 13
maaf kalo salah
