Answer 1

Jawaban:

rumus gradien

m = y2 - y1 / x2 - x1

6. m = 4 - (-5) / -2 - 1

m = 9/-3

m = 3

bentuk lain pers garis:

y - (-5) / 4 - (-5) = x - 1 / -2 - 1

7. y - 2 / -2 - 2 = x - 1 / -2 - 1

8. m = -8 - 0 / 3 - (-1)

m = -8/4

m = -2

9. (2,6) dan (-1,-9)

pers garis:

y - 6/-15 = x - 2/-3

------------------------- bagi -3

y - 6/ 5 = x - 2

2(y - 6) = x - 2

2y - 12 = x - 2

2y = x + 10

10. m = 1 - 5 / -3 - (-2)

m = -4/-1

m = 4

pers garis:

y - 5 / -4 = x + 2 / -1

-1(y - 5) = -4(x + 2)

-y + 5 = -4x - 8

y = 4x + 13
