pleaseeeeeeeee help me :)

Answer:
f(x) = 5 - x has a negative slope.
Step-by-step explanation:
Y = mx + c is the general form for a straight line.
Whem m is negative the slope is negative
Consider f(x) = 5 - x
f(x) = -x + 5
- so the slope is negative.
For g(x) we see that g(x) increases with x so the slope id positive.
