7. The coordinates (1, 1), (2, 4), and (3, 9) are graphed on a coordinate plane. Which statement describes the
relationship between x and y values in the
coordinates?
A. The relationship is proportional because the ratio between x and y is constant for all coordinates.
B. The relationship is not proportional
because the values of y are greater than the values of x.
C. The relationship is proportional because a straight line can be drawn from the origin through the
coordinate (1, 1).
D. The relationship is not proportional because a straight line cannot be drawn through all three coordinates
and the origin.
