The variables y and x have a proportional relationship, and y = 28 when x = 21. What is the value of x when y = 42
x=114
x =18
x= 313
x = 56

What does the sign of the slope tell you about a line?

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)
