what does the slope of the line represent within the context of your graph? what does the y-intercept represent?
test the residuals of two other points to determine how well the line of best fit models the data.
use the line of best fit to you to describe the data correlation.
using the line of best fit that you found in part three, question 2, approximate how tall is a person whose arm span is 66 inches?
according to your line of best fit, what is the arm span of a 74-inch-tall person?

The slope represents how much the height increases.

Step-by-step explanation:   And the y intercept represents the beginning/ smallest length of arm span that can occur in relevance to the height. The y-intercept is where the line crosses the y axis and in context with the problem, a person cannot have a negative height.This is the answer for this part of question

What does the slope of the line represent within the context of your graph? What does the y-intercept represent?

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
