John is trying to save money this year. When he opened his account he had a balance of $300. By the end of the 12 month time span, John had $1500 in his savings account.  Find the rate of change.  Write an equation in slope-intercept form to model this situation.

• y = 100x - 300
• y = 100x + 300
• y = 1/10x + 300
• y = 1/10x - 300
