Answer:
a) 
b) 
c) 5
Step-by-step explanation:
Take y2-y1 over x2-x1 to get the slope of the line
2-5/2-6
-3/-4
3/4
2x -4y=20
-4y=-2x+20
Y= 1/2x - 5 that’s the answer
If there are 272.5 rotations in a mile, and 5280 ft in a mile, then there are 5280 ft in 272.5 rotations. Divide 5280 by 272.5 gives us 19.4 ft/rotation.
That's the circumference of the wheel, and since c = πd, 19.4/π = d, d = 6.2 ft. The diameter of the wheel is how tall it is.
Does this help? Any questions?
