Linear Equation from Tables

The money I have is represented by the equation: y = 10x + 100 where x = number of weeks and y = money remaining. How does my money CHANGE each week?

• increases by $10 each week

• decreases by $10 each week

• increases by $100 each week

• decreases by $100 each week

Write an equation that could represent the amount of money in my account

• y = 0x + 3

• y = 3x

• y = x+3

• y = 3x + 1

Write an equation that could represent the amount of money in my account

• y = 15x + 4

• y = 15x

• y = 15 + 4

• y = 4x + 15

Write an equation that could represent the amount of money in my account

• y = -20x + 5

• y = 5x + 20

• y = 20x + 5

• y = -5x + 20

Write an equation to represent the amount of money I have

• y = 3x + 3.5

• y = 3x -10

• y = -10x + 3

• y = 10x + 3

What is the correct equation for the graph?

• y = x + 5

• x = y
