Linear Correlations from Tables and Graphs

Write an equation from the graph using (p) for price and (w) for weight.

• p = 20w
• w = 20p
• p = 20p
• w = 20w

Which equation matches the table?

• y = x + 5
• y = 5x
• y = x - 5
• x = y - 5

In this equation, what is the y-intercept?

^{y = 3x - 4}

• 3

• -4

• 4

• 3x

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

The money I have is represented by the equation:

y = 95x + 23 where x = number of weeks and y = money remaining.

How much money do I have initially?

• $95

• $95 in debt

• $23

• $23 in debt

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
