Select all that apply:

If two sets of data are proportional to one another:

• the value of every ratio y/x will not be equal

• the graph that represents the data will be a straight line that passes through the origin.

• the graph will contain the points (0, 0) and (1, r) where r is the unit rate.

• there will exist a constant, k, for which you can replace in the equation y = kx
