Unit 3&4 Test Review (Linear Equations) #1

Amy is on a weight loss show. When the show began, she weighed 231 pounds. During the show, she lost 4 pounds per week. Which equation represents the amount of weight she lost?

• y = 4 - 231x
• y = 231x - 4
• y = 231 - 4x 
• y = 4x + 231

An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute.  Write an equation to model the situation.

• y = 30,000ft - 2,000ft(x)
• y = 30,000ft + 2,000ft(x)
• y = 30,000ft(x) - 2,000ft
