F(-5) = -5m+n = -17
f(3) = 3m + n = -1 *Eleminasi
-8m = - 16
m = 2 *subtitusi

-5.2 + n = -17
n = -17+10
n = -7

m-n = 2 - (-7)
= 2 + 7
= 9

F(x) = mx + n
f(-5) = -5m + n
-17 = -5m + n
f(3) = 3m + n
-1 = 3m +  n

-17 = -5m + n
-1 = 3m + n
-16 = -8m
m = 2
n = -7

Maka, nilai dari m - n = 2 -(-7) = 9 (C)
