yang nomor 4 kakkk gimanaaa

h (x) = mx + n
h (-2) = 1 maka
m . (-2) + n = 1
-2m + n = 1 .... Persamaan (1)
h (0) = 5 maka
m. (0) + n = 5
0 + n = 5
n = 5 .... Persamaan (2)

Subtitusi Pers (2) ke (1)
-2m + n = 1
-2m + 5 = 1
-2m = 1 - 5
-2m = -4
m = -4 : -2
m = 2

a) Nilai m = 2 dan n= 5
b) h (x) = 2x + 5
h (-8) = 2. -8 + 5 = -16 + 5 = -11
