Write the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1). Include your work in y
lys-0071 [83]
First find the slope, 
m=(y2-y1)/(x2-x1)=(1-(-9))/(7-6)=10
Next, use the point slope form to find the equation:
L : y-y1=m(x-x1) => y-1=10(x-7) 
    [in point slope form, point is (7,1), slope=m=10 ]

The endurance of both track athletes and gymnasts is recorded in terms of maximum volume of oxygen and is measured in milliliter
Olin [163]
The mean of the track athletes is given by
\frac{89.2+45.3+89.1+57.3+61.5+80.1+47.2}{7}=67.1

The mean of the gymnasts is given by
\frac{72.1+78.5+66.2+47.3+63.1+89.3+65.3}{7}=68.8

The difference in mean is given by
68.8-67.1=1.73 (rounded to one decimal place)
