Elizabeth already had $250 in her savings account and then started saving $10 each week.

A swimming pool has 850 gallons of water in it and is being drained at a rate of 5 gallons each hour.

Write the equation for each situation.

​ (a)   = ​ (b)  

• y = 10x +250

• y = -5x +850

• y = 850x - 5

• y = 5x +850

• y = -10x -250

• y = 10x - 250

• y = 250x + 10

A nonproportional relationship is represented by the equation (a)  

• y = mx + b

• y = kx

• y = b

• y = x
