You can identify the slope which is done by calculating it between two points of the line using the formula which everyone know is y2--y1 and x2--x1
Or you can find the Y intercept which you substitute the slope and the coordinates you have of a point.

I think you put each set of data in to l1 and l2 on your calculator nd find the linear regression ( r value) and you can get to the r value by going to stat diagnostic on
Answer:
4
Step-by-step explanation:
A carpenter uses 4 nails to install each shelve
A) 390/.3= 1300 , 1300-390= 910, 910/1300= .70 OR 1.00-.3= .7
b) 390/.3= 1300$
c)390/.3= 1300 , 1300-390= 910$
Estimation would give you an answer close to the actual answer so you can see if your answer is reasonable depending on how close the estimate is
