Persamaan garis yang melalui titik p(0, 3) adalah...A.2y=8 B.3x+y=3 C.2y+3x=5 D.2y-2x=9

a. 2y = 8, m = 0
persamaan garis :
y-y1 = m(x-x1)
y-3 = 0(x-0)
y-3 = 0
y = 3

b. 3x+y =3, m = -a/b = -3/1 = -3
persamaan garis :
y-y1 = m(x-x1)
y-3 = -3(x-0)
y-3 = -3x + 0
y-3 = -3x
y = 3-3x

c. 2y+3x = 5, m = -a/b = -3/2
persamaan garis :
y-y1 = m(x-x1)
y-3 = -3/2(x-0)
y-3 = -3/2x
_________ x2 (menghilangkan pecahan)
2y-6 = -3x
2y = 6-3x

d. 2y-2x = 9, m = -a/b = -(-2)/2 = 2/2 = 1
persamaan garis :
y-y1 = m(x-x1)
y-3 = 1(x-0)
y-3 = x
y = x+3
