Number of Weeks: 0 2 5 8
Total Amount of Money: 42 52 67 82

Write an equation in standard form that represents the relationship between the number of weeks and the total amount of money Marcus will save.

A. -5x + y = 42
B. -x + 5y = 42
C. x + 5y = 42
D. 5x + y = 42

Answer 1

Marcus currently has $42 and has plans to save an additional $5 each week to buy a pair of shoes. He made a table showing the total amount of money he will have saved for different weeks. Since $5 per week is the slope and $42 is the y intercept

The equation of the line is equal to:

Y = 5x + 42

-5x +y = 42
