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)
