A slope of

means that for every time x goes up by 3, y goes up by 4.
28 - 22 = 6 which is 2 times 3.
while 10-2 = 8 which is 2 times 4.
This fits the slope.
Answer:
the diameter is 4 cm which means the radius is 2 cm. Diameter divided by two will give you the radius. The formulae for circumference is 2 π⋅r. So the circumference would be 4 π.

Answer:
31/40 of the trail
Step-by-step explanation:
he completed 9/10 of the trail (or 72/80 because 9*8 is 72)
He went back 1/8 of the trail (or 10/80 because 1*10 is 10)
72-10 is 62
he went 62/80, simplified is 31/40 of the trail
