Tables and Linear Functions

A store receives 7 new movies per week. Write an equation to find the number of movies "y" the store receives after "x" weeks.

• y = 7x
• x = 7y
• x + 7 = y

Jeff earns $10 per hours raking leaves. Write an equation to find the amount of money "y" he earns for "x" number of hours.

• y = 10x
• x = 10y
• y = x + 7

Pablo has $12. He earns $7 for every lawn he mows. Write an equation to find the amount of money "y" he will have after "x" number of lawns.

• y = 12x + 7
• y = 7x + 12

Elliot wants to sign up for a gym membership. The gym require a $35 fee to sign up, then $12 every month. Write an equation to find the amount Elliot will pay for his gym membership "y" after "x" amount of months.

• y = 35x + 12
• y = 12x + 35
• y = 12x - 35

What is the function of the table?

• y=x+3
• y=x*3
• y=x÷3
• y=x-3

Nancy can type 50 words per minute. Look at the table below to write an equation that matches the data.

• m=50 + w

• w= 50m

• w= 50 + m

• m= 50 - w

Look at the table below. Write an equation to match the pattern between m, minutes and bubbles blown, b.

• b = 12(m)
• b= m +12
• b = m ÷ 12
• none of these

Greg gets paid $6 an hour working in a garden. Use the equation m=6h, where m is the money he makes, and h is the hours he works. How much money does he make if he works 9 hours?

• $15
• $3
• $54
• $53

Write the equation.

• f(x) = -5x + 1
• f(x) = x + 5
• f(x) = -2x
• f(x) = -5x + 6

Write the equation.

• f(x) = 3x - 7
• f(x) = 3x - 1
• f(x) = 3x - 4
• f(x) = 2x + 3
