Jawaban:

1. b. m = -2

c. m = 6

2. b. m = -3

c. m = 2

3. b. m= 3, c = -8

4. a. m = -7

Penjelasan dengan langkah-langkah:

1. b. y = -2x

m = -2

c. 2y = 12x

y = 12x/2

y = 6x

m = 6

2. b. y = 6 - 3x

m = -3

c. 3y = 9 + 6x

y = 9+6x/3

y = 3 + 2x

m = 2

3. b. 3x - 5y - 8 = 0

m = 3, c = -8

4. a. P(2,6) = (x1,y1)

Q(4,-8) = (x2,y2)

[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{ - 8 - 6}{4 - 2} \\ = \frac{ - 14}{2} \\ = - 7[/tex]
