Answer: y = 0.755x is proportional.
Step-by-step explanation: To determine if the equation y = 0.755x is proportional, we need to check if there is a constant ratio between y and x for all values of x.
In a proportional relationship, as x increases or decreases, y also increases or decreases in a consistent manner.
To test if the equation is proportional, we can choose different values of x and calculate the corresponding values of y using the equation.
For example, let's choose x = 2 and x = 5:
When x = 2:
y = 0.755 * 2 = 1.51
When x = 5:
y = 0.755 * 5 = 3.775
To check if the ratio of y to x is constant, we can calculate the ratio of y to x for both values:
When x = 2:
Ratio of y to x = 1.51 / 2 = 0.755
When x = 5:
Ratio of y to x = 3.775 / 5 = 0.755
Since the ratio of y to x is the same for both values, we can conclude that the equation y = 0.755x is proportional.
