Lucas and Brianna read three books each last month The table shows the number of pages in each book and the length of time it took to read the entire book a Show the relationship between the number of pages and hours read
b. Which of the tables, if any, shows a proportional relationship? Explain how you know.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
