2x + 5y = 10
Change to y = mx + b
subtract 2x from both sides
5y = -2x + 10
divide both sides by 5
y = -2/5x + 2
slope = -2/5

Answer:
1st Circle
Radius = 9
Diameter = 18
Circumference = 2 ×
× r = 2 × 3.14 × 9 = 56.52
2nd Circle
Radius = 14
Diameter = 28
Circumference = 2 ×
× r = 2 × 3.14 × 14 = 87.92
