Point ????(−5,8) is reflected across the line ???? = ????. What are the coordinates of ????′? Show your work and explain. 

Suppose point ????(4, −9) is translated according to the rule (????, ????) → (???? + 3, ???? − 2). What are the coordinates of ????′? Explain. 

How many lines of symmetry does a regular heptagon have? Explain your answer. 

Suppose the point ????(2,8) is reflected across the ???? −axis and then translated according to the rule (????, ????) → (????, ???? + 4). What are the coordinates of ????′′? Show your work and explain.
