Jimmy and rick are practicing knot-tying for their rock climbing training.  the number of knots that jimmy can complete in  x  days  is modeled by the function  f(x) = 6x  + 10,  and the number of knots rick can complete in  x  days  is modeled by the function  g(x) = 4x  + 15

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
