Question

Tentukan persamaan garis yang melalui titik
a. A(-2, 3) dan sejajar garis y = -x - 5;
b. B(-4, 0) dan sejajar garis 2x + 3y = 1;
c. D(-3, 1) dan sejajar garis x + 4y + 5 = 0;
d. E(2, 4) dan sejajar garis x = 3y + 3

Answer 1

1. m = -1
y - 3 = -1 (x - (-2))
y - 3 = -1 (x + 2)
y - 3 = - x - 2
y = - x - 2 + 3
y = - x + 1

2. m = - 2/3
y - 0 = -2/3 (x + 4)
y - 0 = -2/3x - 8/3
y = -2/3x - 8/3

3. m = -1/4
y - 1 = -1/4 (x + 3)
y - 1 = -1/4x - 3/4
y = -1/4x -3/4 + 1
y = -1/4x + 1/4

4. m = 1/3
y - 4 = 1/3 (x - 2)
y - 4 = 1/3x - 2/3
y = 1/3x - 2/3 + 4
y = 1/3x + 10/3

sorry klo salah, ya...
