Writing Linear Equations

Jacob conducts an egg-drop experiment. He drops it from 32 feet in the air and it falls at 4 feet per minute. Write a linear equation to represent this situation.

• y = -4x+32

• y = 32x+4

• y = -4x+8

• y = -8x+32

An airplane is 30,000 feet above ground and descends at the rate of 2,000 feet per minute. Write a linear equation to represent this situation.

• y = 2,000x-30,000

• y = -2,000x+15

• y = -30,000x+15

• y = -2,000x+30,000

Michael has $650 in his savings account. He withdraws $50 each week. Write a linear equation to represent the relationship between the weeks and the total money left in his savings account.

• y = -650x+50

• y = -50x+650

• y = 13x + 50

• y = -13x+650

• 5

A train is 500 meters above ground and descends at the rate of 50 meters per minute. Write a linear equation to represent this situation.

• y = 50x-500

• y = -50x+500

• y = -500x+50

• y = 50x+500

John has $800 in his savings account. He withdraws $100 each week. Write a linear equation to represent the relationship between the weeks and the total money left in his savings account.

• y = -800x+100

• y = -100x+800

• y = 8x + 100

• y = -8x+800
