Thus, there are 476 pedal turn in one mile.
Answer:
Runners that decrease times are not improving
Step-by-step explanation:
Answer:
y=3/2x+4
Step-by-step explanation:
1.find the slope
y2-y1/x2-x1
-5-1/-6-(-2)
-5-1/-6+2
-6/-4
3/2
slope (m) is 3/2
2.y-y1=m(x-x1)
y-1=3/2(x-(-2))
y-1=3/2(x+2)
y-1=3/2x+6/2
y=3/2x+6/2+1
y=3/2x+8/2
y=3/2x+4
