Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In this problem we have a proportional variation
Let
y ----> the pay in dollars
x ----> the number of hours worked
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin.
The slope or constant of proportionality in this problem is equal to
substitute
The algebraic expression is equal to
