Lesson 25: Linear Graphing

Caleb started saving money in a cookie jar. He started with $25. He adds $10 to the account each week. Write an equation where w is the number of weeks and t is the total amount in the account.

• t = 25w + 10

• t = 10w + 25

• w = 25t + 10

• w = 10t + 25

Caleb started saving money in a cookie jar. He started with $25. He adds $10 to the account each week. Determine which variable is independent and which is dependent. (choose two answers)

• independent: t

• independent: w

• dependent: t

• dependent: w

Kevin is taking a taxi from the airport to his home. There is a $6 flat fee for riding in the taxi. In addition, Kevin must also pay $1 per mile. Write an equation where m is the number of miles and t is the total cost of the taxi ride.

• t = m + 6

• t = 2m + 6

• m = t + 6

• m = 2t + 6

Anna started with $10. She saved an additional $5 each week. Write an equation that can be used to determine the total amount saved, t, after a given number of weeks, w.

• t = 5w + 10

• t = 10w + 5

• w = 5t + 10

• w = 10t + 5

Aliyah is purchasing produce at the farmers’ market. She plans to buy $10 worth of potatoes and some apples. The apples cost $1.50 per pound. Write an equation to show the total cost of the produce, where t is the total cost and a is the number of pounds of apples.

• t = 10a + 1.5

• t = 1.5a + 10

• a = 1.5t + 10

• a = 10t + 1.5
