A residual plot is shown for a model of y based on x. Points are P(0, -2), Q(1, -1), R(2, 0), S(3, 1), and T(4, 2). Which statement is most accurate?
A
The residuals form a steady upward pattern, so the model may not capture the relationship fully.
B
The residuals prove the model is exact for all x-values.
C
The model overpredicts only at the greatest x-value.
D
The residuals are all too large to be useful.
