Answer 1

Jawab:

1. y= 4x -10 (A)

2. y = 3x-15 (C)

Penjelasan dengan langkah-langkah:

1. Sejajar y= 4x - 5

melalui (3,2)

m1= 4

m2= 4

y-y1=m(x-x1)

y-2=4(x-3)

y-2=4x-12

y= 4x -12+2

y= 4x -10 (A)

2. Sejajar 3x -y+5 =0 melalui (4, -3)

m1 = -3/-1 = 3

m2= 3

y-y1= m(x-x1)

y-(-3) = 3(x-4)

y+3 = 3x -12

y= 3x -12 -3

y = 3x-15 (C)
