You get a raise on your allowance of $5/month, as long as you maintain good grades. After 7 months you have an allowance of $65. Write an equation in point slope form for the situation:
The equation would be y=5x+30 x= the months. You multiply 7*5 to see how much things increased, which was by 35. This means that to equal 65 you had to start with 30, so 30 becomes the base price.
