Solving Linear Relations Problems

Bob has $150 in his savings account and saves $40 per month.

• y = 150 + 40

• y = 40x + 150

• y = 150x + 40

Easy Car Rental charges $8.50 an hour plus a rental fee of $25.50.

• y = 8.5 + 25.5

• y = 8.5x + 25.5

• y = 8.5 + 25.5x

• y = 8.5x + 25.5x

Write an expression for the following. Jerry has $20 and makes $7 per hour.

• y = 7x + 20

• y = 7 + 20x

• y = 20 + 7

• y = 20x + 7x

A man is climbing down from 100 feet high descending 30 feet per minute.

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30
