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

.
I think for number 3, it is the third option.
1 + (-5) becomes 1 - 5 because you are adding a negative number.
1 - 5 is -4
Answer:
no its not

from 2 random samples you cant figure it out
Answer: 76%
Explanation: 55/72.00 x __/100= 5,500
5,500 divided by 72.00= 76.3888889
