5x + 1 = -2x -8
7x= -9
x= -9/7
The distance between two points is calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values from the given above,
d = √(4 - -4)² + (4 - -4)²
d = 8√2 = 11.31
The distance between the points is approximately equal to 11.31. The value that Jason presented is not the real distance because it does not account for the other set of coordinates.

The significance of "b" in exponential function
An exponential function is represented as:
![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
In the above equation, parameter "b" is the rate of the function
In other words, the constant multiplier of the function.
Take for instance;
![y = 2*4^x](https://tex.z-dn.net/?f=y%20%3D%202%2A4%5Ex)
By comparison:
![b = 4](https://tex.z-dn.net/?f=b%20%3D%204)
Another instance is:
![y = 2(-4)^x](https://tex.z-dn.net/?f=y%20%3D%202%28-4%29%5Ex)
By comparison
![b = -4](https://tex.z-dn.net/?f=b%20%3D%20-4)
<u>Other significance of parameter b are:</u>
If
then b represents a growth factor
If
the b represents the factor of decay
i.e. b is never 0
