In a proportional relationship, the ratio of the y-values to the x-values remains constant. Let's check if this is the case:
For x=3, y=1.5; the ratio y/x = 1.5/3 = 0.5
For x=5, y=2.5; the ratio y/x = 2.5/5 = 0.5
For x=7, y=3.5; the ratio y/x = 3.5/7 = 0.5
Since the ratio y/x is the same for all values, we can conclude that the table represents a proportional relationship.
For x=3, y=1.5; the ratio y/x = 1.5/3 = 0.5
For x=5, y=2.5; the ratio y/x = 2.5/5 = 0.5
For x=7, y=3.5; the ratio y/x = 3.5/7 = 0.5
Since the ratio y/x is the same for all values, we can conclude that the table represents a proportional relationship.
Answer
what is the unit rate

The unit rate is the constant ratio between the y-values and the x-values, when expressed as a ratio or fraction. In this case, the unit rate is the ratio 0.5 or the fraction 1/2. It represents the amount of y per one unit of x.
