With of the rink is 9 yards.

Area of a rectangle is computed by multiplying length by its width.

A = lw

A = 900 yd²
l = 100 yd
w = ?

900 yd² = 100yd * w
900 yd² / 100 yd = w
w = 9 yd

to check:
900 yd² = 100 yd * w
900 yd² = 100 yd * 9 yd
900 yd² = 900 yd²

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
