Final answer:
To write an equation for the charges, use Y = 200x + 500. The graph of this equation is a straight line with a slope of 200 and a y-intercept of 500.
Step-by-step explanation:
To write an equation for the charges, we can let x represent the number of days. The equation for the charges would then be: Y = 200x + 500, where Y represents the total charges. To graph this equation, we can plot several points by selecting different values for x and calculating the corresponding Y values. For example, if x = 0, then the total charges would be $500. If x = 1, then the total charges would be $700 (200 * 1 + 500). We can continue this process to generate more points and then plot them on a coordinate plane. The resulting graph would be a straight line with a slope of 200 and a y-intercept of 500.
