Use the table and image to answer the question.
Employee 1
Earnings per Hour
Hours Earnings
1 10
2 20
3 30
A line graph is titled as Employee 2, Earnings per Hour. The x-axis is labeled Hours ranging from 0 to 6 in increments of 1. The y-axis is labeled Earnings in dollars, ranging from 0 to 80 in increments of 5. A solid line joins four plotted points. The coordinates of the plotted points are as follows: left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 15 right parenthesis, left parenthesis 3 comma 45 right parenthesis, and left parenthesis 5 comma 75 right parenthesis.
The proportional relationship for the earnings and hours worked for Employee 1 is displayed in the table. The proportional relationship between the earnings and hours worked for Employee 2 is displayed in the graph. What is the equation that represents the proportional relationship between the earnings and hours worked for Employee 1 and Employee 2?
For Employee 1, the earnings per hour is consistent at $10. This means the equation representing the proportional relationship is Earnings = 10 * Hours.
For Employee 2, the earnings per hour increases by $15 for each additional hour worked. The equation representing the proportional relationship is Earnings = 15 * Hours.
Therefore, the equations representing the proportional relationship between the earnings and hours worked for Employee 1 and Employee 2 are:
Employee 1: Earnings = 10 * Hours
Employee 2: Earnings = 15 * Hours
