Question

The table of values represents a linear function g(x), where x is the number of days that have passed and g(x) is the balance in the bank account:
х
g(x)
0 $325
5
$400
10 $475
Part A: Find and interpret the slope of the function (3 points)
Part B: Write the equation of the line in point-slope, slope-intercept, and standard forms. (3 points)
Part C: Write the equation of the line using function notation. (2 points)
Part D: What is the balance in the bank account after 12 days? (2 points)

Answer 1

Answer:

Part A: 15

Part B: -720 = 40x

g(x) + 600

40x - y + 600 = 0
