An investor invests $525 in stock. The stock is projected to increase at a rate of $25 per month. Create a model in slope intercept form (write an equation) to represent the total value of the stock, f(x), based on the number of months, x.
Identify the slope of the linear relationship. Explain what this means in the context of the problem.
Identify the y-intercept of the linear relationship. Explain what this means in the context of the problem.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

the answer is b.6
