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

Jacob collects hats.  He has 6 hats already, and he collects 2 hats a week. Write an equation in slope-intercept form that models this situation.

• y = 2x + 6
• y = 6x + 2
• y = 2x - 6
• y = 6x - 2
