Can somebody help me with this please?

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

Which of the following represents the range of the graph of f(x) below

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
