Help! help! help! okay i need help im in algebra 2 and i have to make a scatter plot or something if you can help me answer & ill ask you how to do it in the comments

please do not answer just for points i really need help its due today at 12:00 noon and my teacher gave me an extra week last week and now its due and idk how to do it help

Part I:

The data collected is:

Height (X) Arm Span (Y)

   71               73

   62               63

   63               66

   72               70

   66               66

   64               64

   67               70

   60               64

   65               67

   66               64

   67               65

Part II:

The scatter plot, the predicted line of best fit is shown below.

Part III:

The variable plotted on the x-axis is the height of a person and the variable plotted on the y-axis is the arm span.

This is because in this case we are performing an analysis to determine whether the length of human's arm span is correlated to their height.

The two points that were used to draw the lines of best fits were (62, 63) and (72, 70).

The equation of the line passing through those two points using the point-slope formula is:

Thus, the equation of the line is y = 0.70x + 43.4.

plzzz let me know if that helped a little

what is a scatter pot and how do u do them

Step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
