Maggie only wore sandals tracker on two of the days that she trained so from her fitness trackers she verified that on the third
KIM [24]
We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that <span>on the eighth day she biked 35 miles, so our second point is (8,35).

To relate our two point we are going to use the slope formula: </span>m= \frac{x_{2}-x_{1}}{y_{2}-y_{1}}
We can infer form our points that x_{1}=3, y_{1}=20,x_{2}=8, and y_{2}=35. so lets replace those values in our slope formula:
m= \frac{35-20}{8-3}
m= \frac{15}{5}
m=3

Now that we have the slope, we can use the point-slope formula <span>determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: </span>y-y_{1}=m(x-x_{1})
y-20=3(x-3)
y-20=3x-9
y=3x+11

We can conclude that the equation of the line that  best fit the set for Maggie’s data is y=3x+11.

7/8+9/10=71/40=1 31/40
1/4+2/3=11/12
1/2+1/4 is different from 1/2+1/3 because 
1/2+1/4= 2/4+1/4=  5/1 =1  1/4
1/2+1/3=3/6+2/6=5/6
