Answer:
y = 10 + 2.50h
$25
Step-by-step explanation:
first the equation is written as such because she pays $10 no matter how many hours she rides. She also pays 2.50 for each hour so use h as the variable to define number of hours she rides the bike.
since equation is y = 10 +2.50h
and h = 6 hours, substitute and find the total cost
y = 10 + 2.50(6)
= 10 + 15
= $25

Answer:
   Either of ...
- (x, y) ⇒ (-x, -y)
- Rotation 180° about the origin
Step-by-step explanation:
There are at least two ways to express the transformation that maps each coordinate to its opposite.
   1. reflection across the origin: (x, y) ⇒ (-x,-y)
   2. rotation 180° (either direction) about the origin.
Take your pick.
