You are told that a bank investment can be modeled by a linear equation. The slope of the linear equation is positive and the value for b in the equation is 30,000. What can be said about the initial investment, and is the money increasing or decreasing, based on the information given?

If the investment can be modeled by a linear equation, the slope positive, and the value for the y-intercept is at 30,000, the equation of the line is
y = mx + 30,000
where m > 0

The initial investment is when x is 0 or the y-intercept. Therefore, the initial investment is $30,000

Since the slope of the line is positive, this means that the investment will increase through time.
