1.Garis yang melalui titik A(−2, 3) dan B(2, p) memiliki kemiringan 2per1 .Tentukan nilai p. 2. Kemiringan garis yang melalui titik (4, h) dan (h + 3, 7) kemiringan − 4 per 1 Tentukan nilai h.

1. kemiringan = 2/1 = 2 gunakan rumus y2 - y1 = p - 3 = p - 3 = p - 3 x2 - x1 2 - (-2) 2 + 2 4 p - 3 = 2 4 p - 3 = 4 x 2 = 8 p = 8 + 3 = 11
2. m = -4/1 = -4
3,7 - h = -4 h - 4 3,7 - h = -4h + 16 3h = 16 - 3,7 = 12,3 h = 12,3/3 h = 4,1

1. m = y₂ -y₁ / x₂ -x₁ 2/1 = p -3 / 2 -(-2) 2/1 = p -3 / 2 +2 2/1 = p -3 / 4 8 = p -3 8 +3 = p p = 8 +3 p = 11 Jadi, nilai p = 11
2. m = y₂ -y / x₂ -x₁ -1/4 = 7 -h / h +3 -4 -1/4 = 7 -h / h -1 -h +1 = 28 -4h -h +4h = 28 -1 3h = 27 h = 27/3 h = 9 Jadi, nilai h = 9.
gunakan rumus y2 - y1 = p - 3 = p - 3 = p - 3
x2 - x1 2 - (-2) 2 + 2 4
p - 3 = 2
4
p - 3 = 4 x 2 = 8
p = 8 + 3 = 11
2. m = -4/1 = -4
3,7 - h = -4
h - 4
3,7 - h = -4h + 16
3h = 16 - 3,7 = 12,3
h = 12,3/3
h = 4,1
2/1 = p -3 / 2 -(-2)
2/1 = p -3 / 2 +2
2/1 = p -3 / 4
8 = p -3
8 +3 = p
p = 8 +3
p = 11
Jadi, nilai p = 11
2. m = y₂ -y / x₂ -x₁
-1/4 = 7 -h / h +3 -4
-1/4 = 7 -h / h -1
-h +1 = 28 -4h
-h +4h = 28 -1
3h = 27
h = 27/3
h = 9
Jadi, nilai h = 9.
