Nadea has $600 in her savings account. She withdraws $35 per week to buy gas for her car. Which equation can be used to determine how many weeks, w, it will take for Nadea to reduce her balance to $285?

• (600 – 35)w = 285 

• 35w – 600 = 285 

• 600 – w = 285 

•  600 – 35w = 285

Write the equation of the line.

• y= -1x-3

• y= -3x-1

• y=(-1/3)x-1

• y= -3x-3

Write the equation.

• y = 4x + 3

• y = 4x -3

• y = 3x + 4

• y = 8x + 2
