At the halftime show, a marching band marched in formation. The lead drummer started at a point with coordinates (–2, –5) and moved 3 steps up and 1 step right.
a. Write a rule to describe the translation.
b. What were the coordinates of the drummer's final position? (3 points)
The rule is (initial x-position + x-displacement, initial y-position + y-displacement). The current coordinates of the lead drummer are (-2 + 1[step], -5 + 3[step]).
