Given the following equation:
[tex]\text{ V = 23.4 + 2.8x}[/tex]
In the standard slope-intercept form, y = mx + b, m represents the slope of the equation.
If the slope is positive, it is increasing.
If the slope is negative, it is decreasing.
From the given equation, V = 23.4 + 2.8x, it appears that 2.8 is the slope in this equation. Since it is a positive number, it is increasing.
Therefore, we can say that:
The value of this investment is increasing at a rate of 2.8 thousand dollars per month.
