Triangle obc is a right triangle drawn on a coordinate plane. side oc lies on the x-axis, the coordinates of point o are (0, 0), and the coordinates of point b are (6, 8).

sin ∠boc =
tan ∠boc =

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)
