answer: (0, 3)
the y-intercept is where the line intercepts (crosses) the y-axis (up/down axis).
the line crosses the y-axis at 3. when x = 0, y = 3
the general formula for compound interest is
a = p(1 + r/n)^nt where p = initial amount, r = yearly rate ( as a fraction), t = number of years and n = number of times in the year that interest is added.
so for the given data:
amount after 1 year = 500 ( 1 + 0.05/365)^365
