You are given a graph that models a ball being thrown in the air. the vertical axis is the height of the ball from the ground and the horizontal axis is time in seconds. the ball goes up and comes back down to hit the ground. is the graph of the ball going to be a constant , increasing, decreasing, or a combination of the three? does the graph have a maximum or minimum point?

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?
