A graph is a straight line through the point (0, 5). Can the graph represent a proportional relationship? Explain.
A.


Yes; the constant of proportionality is 5.
B.


Yes; the equation of the line can be written in the form y = kx, where k = 5.
C.


Yes; the graph is a straight line that crosses the y-axis at (0, 5).
D.


No; the graph of a proportional relationship must pass through (0, 0).
