Linear vs. Exponential

A store receives 7 new movies per week. Write an equation to find the number of movies "y" the store receives after "x" weeks.

• y = 7x
• x = 7y
• x + 7 = y

• y = 10x
• x = 10y
• y = x + 7

Pablo has $12. He earns $7 for every lawn he mows. Write an equation to find the amount of money "y" he will have after "x" number of lawns.

• y = 12x + 7

A camp charges families a fee of $625 per month for one child and a certain amount more per month for each additional child. Use the graph to write an equation in slope-intercept form to represent the amount a family with x additional children would pay.

• y = 625x + 225
• y = 225x 
• y = 225x + 625
• y =  625
