Answer:
y = 1/5x + 2
Step-by-step explanation:
y = 1/5x + b
4 = 1/5(10) + b
4 = 2 + b
2 = b
Length = 2x - 5
Width = x
Perimeter = 146
P = 2L + 2W
146 = 2(2x - 5) + 2x
146 = 4x - 10 + 2x
146 = 6x - 10
146 + 10 = 6x
156 = 6x
156/6 = x
26 = x
Length = 2(26) - 5
Length = 52 - 5
Length = 47 cm
Width = 26 cm
