The phone company Blurizon has a monthly cellular plan where a customer pays a flat fee for unlimited voice calls and then a certain amount per GB of data used. If a customer uses 6 GB, the monthly cost will be $51. If the customer uses 20 GB, the monthly cost will be $93. A) Find an equation in the form y = m x + b , where x is the number of GB of data used in a month and y is the total monthly cost of the Blurizon plan. Find both the Point-Slope (use first point) and the Slope Intercept form of the line:

Point Slope form:

Slope Intercept form:

B) Use your equation to find the total monthly cost if 10 GB are used. If 10 GB are used, the total cost will be dollars.
