Answer:
y, x are variables
b₀ and b₁ are constants
Step-by-step explanation:
If y=b₀+b₁x where x and y are variables.
The variable y is the sum of a constant b₀ and varies directly with variable x where b₁ is the constant of proportionality of x with y.
The higher the value of x, the higher the value of y.
A typical example of this is applied in the case of a Sales Person whose take home is dependent on a base Salary and the Monthly Volume of Sales. The base salary is the constant b₀ and the Monthly volume of sales is x where b₁ will be the rate of commission on sales.
