Question

1. Which two points did you use to draw the line of best fit?
2. Write the equation of the line passing through those two points using the point-slope formula
y - y1 = m(x - x1). Show all of your work. Remember to find the slope of the line first.
3. What does the slope of the line represent within the context of your graph?
4. Using the equation that you found in question 2, approximately how tall is a person whose arm span is 66 inches?
5. According to your line of best fit, what is the arm span of a 74-inch-tall person?

Answer 1

so would my two points be 68 and 73
;

Answer 2

68 and 73 aren't points. Points in a coordinate grid are in the form (x, y)

Answer 3

oh :P

Answer 4

so # 1. is points (x,y)???

Answer 5

or did i understand that rong???

Answer 6

I'm sorry I took so long. A point is made up of an x and y coordinate; remember its graphing both height and arm span.
