Which of these pairs of points defines a line with a slope -4/3?A) (-1, 6) and (-4, 10)
B) (6, -1) and (-4, 10)
C) (-1, 6) and (10, -4)
D) (6, -1) and (10, -4
Answers
The point pair establishing a line with a slope of -4/3 is (-1, 6) and (-4, 10). which is the correct answer would be an option (A).
What is the slope of the line?
The slope of a line is defined as the gradient of the line.
To determine the slope of a line, we can use the formula: slope m = (y₂ - y₁)/(x₂ -x₁ )
Using this formula, we can calculate the slope for each of the pairs of points given:
A) (-1, 6) and (-4, 10):
slope = (10 - 6)/(-4 - (-1)) = -4/3
B) (6, -1) and (-4, 10):
slope = (10 - (-1))/(-4 - 6) = -11/10
C) (-1, 6) and (10, -4):
slope = (-4 - 6)/(10 - (-1)) = -10/11
D) (6, -1) and (10, -4):
slope = (-4 - (-1))/(10 - 6) = -3/4
Therefore, the pair of points that defines a line with a slope of -4/3 is (-1, 6) and (-4, 10).

Slope is defined as (y2-y1)/(x2-x1)
"A" gives a slope of (10-6)/(-4-(-1))=4/-3=-4/3

However, the problem states that each chicken laid the same number of eggs, 4. This means, the constant of proportionality is 4, that is .
Therefore, the equation that could be used to the total number of eggs collected from the cop is
In words, the total number of eggs collected is 4 per chicken.
