Ewan is building a maze for his pet rats out of wood. he needs two pieces that are 2 ¾ feet long, one that is 3.5 feet long and two that are 1 5/8 feet long. ewan can buy wood that is 84 inches long at $2.85 per board, 96 inches long that costs $3.80 for each board, or 10 feet long, for $4.61.

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
