diketahui g(x) = mx + n. jika g(2) = 1 dan g(3) = - 1, nilai m dan n berturut-turut...

g(2) = 1 ----> 2a + b = 1
g(3) = -1 ----> 3a + b = -1
----------------->_________ _

------------------> -a = 2
------------>m = a = -2

3a + b = -1
3(-2) + b = -1
-6 + b = -1
b = -1 + 6
n = b = 5

(m,n) = (-2,5)

Bentuk Umum = -2x + 5

g(x) = mx + n

g(2) = 2m + n = 1
g(3) = 3m + n = -1
----------------------- -
-m = 2
m = -2

2m + n = 1
2(-2) + n = 1
-4 + n = 1
n = 4 + 1 = 5

semoga dapat membantu
