Raquel drew a scatter plot to show the relationship between the length, in inches, and weight, in pounds, of metal bars in her shop. Using regression, Raquel fit a line to her scatter plot as shown below. y = 73x

y = 43x

y = 34x

y = 37x

y=3/7x

Step-by-step explanation:

y=3/7x

Step-by-step explanation:

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
