I failed these questions on my classwork yesterday so I need to see what I did wrong so please explain your answer.

10. Determine the equation ofthe line that contains the two points ( 5, 2) and (6, 1). Write the equation of the line in slope-intercept form. {} Bonus: Is this function increasing or decreasing? 11. A plumber charges $42.50 per hour plus a flat fee of $75 to work on a job. Write a linear equation that models the total cost, C(x) of the job where \"x\" represents the number of hours the plumber works. (i The total cost is C(x) = 12. The Louisville zoo sells tickets for $10 each, with children receiving a discount of $5.00. One rainy day the zoo sold 495 tickets and took in 53230 in revenue.
