Answer:
A
Step-by-step explanation:
A linear function describes a straight line with constant gradient. Hence A is the answer as it has a constant gradient of -1 .
B is wrong as the graph has an undefined gradient.
C is wrong as it has an increasing gradient.
D is wrong as it does not have a constant gradient too.
Step-by-step explanation:
straight line = 180 degree
example
1) 2w - 24 + 2w - 40 = 180
4w = 180 + 24 + 40
4w = 244
w = 244/4
.......
2) 13n - 11 +(-9 + 12n)
13n - 11 -9 + 12n = 180
25n -20 = 180
25n = 180 + 20
25n = 200
n = 200/25
