seth and karen are college students who take on different jobs for income. seth needs $750 for expenses and savings each month; karen needs $700. seth has a part-time job where he earns $7.50 per hour. he also mows lawns and earns $15 per lawn that he mows. his monthly earnings can be expressed with the equation 7.50x + 15y = 750, where x is the number of hours seth works and y is the number of lawns he mows. karen has a part-time job babysitting, where she earns $6 per hour. she also walks dogs and earns $4 per dog that she walks. her monthly earnings can be expressed with the equation 6x + 4y = 700, where x is the number of hours karen works and y is the number of dogs she walks. before you begin, decide with your partner who will work with seth's information and who will work with karen's information. working with the equations work separately each partner must change the equation that represents his or her chosen college student to slope-intercept form. identify the slope and y-intercept of the equation. be sure to show all your work. describe how you would graph this line using the slope-intercept method. be sure to write using complete sentences. write the equation in function notation. explain what the graph of the function represents. be sure to use complete sentences. graph the function. on the graph, make sure to label the intercepts. you may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology. comparing students work together each partner now has an equation, function, and graph that represent the combinations of activities resulting in the income needed for each student. compare these items and answer the following questions: which student, seth or karen, has the higher slope when the graphs of their earnings are compared? how can you tell? whose graph, seth's or karen's, has a greater y-intercept? what does that mean for this person? if both students work 80 hours for the month, is the number of lawns seth has to mow greater than or less than the number of dogs karen has to walk? justify your answer. karen begins charging $8 per hour for babysitting and seth begins earning $8 per hour. how does this change affect their graphs if everything else remains the same?
