Answer:
D.
(0,5) and (-4,2)
E.
(-4,4) and (-1,7)
Step-by-step explanation:
To solve this problem, we apply the slope formula and compare with the known slope to see if the answer tallies;
Slope =
A.
(0,5) and (-4,8)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 8
Slope = =
B.
(6,-1) and (10,2)
x₁ = 6 y₁ = -1
x₂ = 10 y₂ = 2
Slope = =
C.
(1,5) and (4,7)
x₁ = 1 y₁ = 5
x₂ = 4 y₂ = 7
Slope = =
D.
(0,5) and (-4,2)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 2
Slope = (2-5) / (-4-0) = 3/4
E.
(-4,4) and (-1,7)
x₁ = -4 y₁ = 4
x₂ = -1 y₂ = 7
Slope = =
Answer:
Carolyn's mistake was confusing the selling price of the necklaces with the profit.
Step-by-step explanation:
Let
x-------> the selling price of each necklace
we know that
The linear equation that represent the situation is equal to
solve for x
The profit on each necklace is equal to
therefore
Carolyn's mistake was confusing the selling price of the necklaces with the profit.
