Find constant of proportionality (graphs)

<p>At a used book store, the owner has priced the books such that the store will earn the same amount of profit on each book it sells. The following graph represents the proportional relationship between the number of books sold (`x`) and the profit made from selling those books (`y` dollars). </p> <linegraph data-props='{"options":{"x_min":0,"y_min":0,"y_max":40,"x_max":32,"cell_size":35,"x_interval":4,"y_interval":5,"x_label":"Number of Books","y_label":"Profit (dollars)","title":"Book Store Profit","x_axis_name":"x","y_axis_name":"y"},"points":[{"id":0,"x":0,"y":0,"show_point":false,"highlight_point":false,"show_coordinates":false,"show_x_intercept":false,"show_y_intercept":false,"x_coordinate_highlight":false,"y_coordinate_highlight":false,"show_x_intercept_point":false,"show_y_intercept_point":false},{"id":1,"x":4,"y":5,"show_point":false,"highlight_point":false,"highlight_point_color":"#A3A3B3","show_coordinates":false,"x_coordinate_highlight":false,"y_coordinate_highlight":false,"show_x_intercept_point":false,"show_y_intercept_point":false,"show_x_intercept":false,"show_y_intercept":false},{"id":2,"x":32,"y":40,"show_point":false,"highlight_point":false,"highlight_point_color":"#A3A3B3","show_coordinates":false,"x_coordinate_highlight":false,"y_coordinate_highlight":false,"show_x_intercept_point":false,"show_y_intercept_point":false,"show_x_intercept":false,"show_y_intercept":false}],"line_segments":[{"first_point_id":0,"second_point_id":2,"show_start_arrow":false,"show_end_arrow":true,"highlight_line":"#A3A3B3"}]}'></linegraph> <p>What is the constant of proportionality for this relationship, as shown in the graph?</br><highlight data-color="#666" data-style="italic">Write your answer as an exact decimal or simplified fraction.</highlight></p>

Understanding and solving the constant of proportionality (graphs) practice problems is an important concept in mathematics for your students because it allows them to understand and analyze relationships between different variables, make predictions about how variables will change over time, and make informed decisions based on the behavior of different systems. Having practice problems on this topic will help students to practice and reinforce the knowledge of this concept and apply it to real-world situations.
