F(x)=x+4
f(x)=-y+4
f(x)=-x-4
f(x)=y-4
Answer:
Step-by-step explanation:
The slope of a line is always rise over run.
To find the slope of this line, we are looking for two points that are on an integer x value and an integer y value.
One of these points is (-4, 1). Another one is (0, -2).
Studying the y-values of both (the rise), the change in y is 
, and since we are going down, the change is 
.
Studying the x values of both (the run), we can see that the rate of change is 
.
So the rise over run will be 
, or just . This is also the slope as slope is rise over run.

The value of f(15), to the nearest hundredth is 253.88
The standard exponential equation is given as:
If f(4.5) = 16, then;
16 = ab^4.5 ..............1
Similarly, if f(9.5) = 60, then:
60 = ab^9.5 ........................... 2
Dividing both equations will give:
60/16 = ab^9.5/ab^4.5
60/16 = b^9.5-4.5
60/16 = b^5
3.75 = b^5
b = 1.3
Get the value of a. Recall that;
60 = ab^9.5
60 = a(1.3)^9.5
60 = 12.09a
a = 60/12.09
a = 4.96
Get the value of f(15)
f()15 = 4.96(1.3)^15
f(15) = 4.96(51.18)
f(15) = 253.88
Hence the value of f(15), to the nearest hundredth is 253.88

The answer is 3.1. First you do 15.5 and divide it by 5. you get 3.1. To double check you do 3.1 x 5 = 15
