Tolong bantuannya dengan jalan yaa ,#pelajaran guru killer

1.a y2-y1 / x2-x1 = 0-0/2-0=0/2 = 0
b.pakai cara yg sama= -2-6/5-6= -8/-11

2. maaf gatau

3. y-2x+11=0 (-2,1)
3y+x-5=6
3.0 + x =11
x =11
3y+x-5=6
3y+11-5=6
3y=0
y = 0
(11,0)

Soal nomer 1
Subnomer a.
[tex]m= \frac{y_1}{x_1} [/tex]
[tex]m= \frac{0}{2} [/tex]
[tex]m=0[/tex]
Subnomer b.
[tex]m= \frac{y_2-y_1}{x_2-x_1} [/tex]
[tex]m= \frac{-2-6}{5+3} [/tex]
[tex]m= \frac{-8}{8} [/tex]
[tex]m=-1[/tex]

Soal nomer 2
3x - 2y + 1 = 0
-2y = -3x - 1
  m = 3/2

Karena sejajar, maka gradiennya sama.
Maka, persamaan garisnya:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-4= \frac{3}{2}(x-1)[/tex]
[tex]y-4= \frac{3}{2}x-\frac{3}{2}[/tex] (dikali 2)
[tex]2y-8=3x-3[/tex]
[tex]3x-2y+8-3=0[/tex]
[tex]3x-2y+5=0[/tex]
