A student uses a graphing calculator to solve the system y=x2−4x+1y = x^2 - 4x + 1 and y=2x−5y = 2x - 5. The calculator displays the intersection points as (2.449,−0.102)(2.449, -0.102) and (1.551,−1.898)(1.551, -1.898). When the student substitutes x=2.449x = 2.449 into the first equation, they get y=−0.097y = -0.097, but substituting into the second equation gives y=−0.102y = -0.102. What is the most likely explanation for this discrepancy?
