tolong dongg kalau bisa sama caranya

1. 4x + 2y - 10 = 0
2y = -4x + 10
y = -2x + 5 (a)

2. b. -1 (aturannya begitu)

3. (4,2) dan (2,5)
[tex]m \: = \frac{y2 - y1}{x2 - x1} [/tex]
m = (5-2) / ( 2-4) = - 3/2 (a)

4. 3y = 6x - 9
y = 2x - 3
P(2,a)
a = 2.2 - 3 = 4-3 = 1 (a)

5. 6x + 2y = -12
2y = -6x + 12
y = -3x + 6. m = -3. (d)

6. b. 7y = -5x

7. d. y = -2x - 2

8. b. y = -x -4
