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 a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of hours worked
y ----> the amount paid in dollars
In this problem we have a proportional variation, between two variables, x, and y
<em>Find out the constant of proportionality k</em>
For (5,300) -----> ---->
For (4,240) -----> ---->
For (6,360) -----> ---->
The constant k is
The equation is equal to
The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation
therefore
