The date of the first sighting of robins has been occurring earlier each spring over the past 25 years at a certain laboratory. Scientists from this laboratory have developed two linear equations, shown below, that estimate the date of the first sighting of robins, where x is the year and y is the estimated number of days into the year when a robin can be expected. Complete parts a and b. (Hint: 2000 was a leap year.)
y = 698−0.304x
y = 1539−0.736x
Solve this system of equations to find the year in which the two estimates agree.
