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>

We can infer form our points that 

, 

,

, and 

. so lets replace those values in our slope formula:



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>




We can conclude that the equation of the line that  best fit the set for Maggie’s data is

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
        
             
        
        
        
Y=3/4x+1/4 if you take a close look at where the line crosses over the y-axis.
        
             
        
        
        
1(1)/(4)-:3= 5/12
5/12 of a cup or 0.146 with a bar on top because the 6 goes on forever.
 
        
             
        
        
        
Yes, because both of them have a 70 degree angle on T and W
