AC is not perpendicular to XZ, because the slope of AC is -1 and the slope of XZ is 2/3. Hence, the correct answer options are:
B. Is not
A. -1
<h3>How to calculate the slope of any straight line?</h3>Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
For the slope of AC, we have:
Point at A = (-1, 3)
Point at C = (4, -2)
Slope, m of AC = (-2 - 3)/(4 - (-1))
Slope, m of AC = (-2 - 3)/(4 + 1)
Slope, m of AC = -5/5.
Slope, m of AC = -1.
For the slope of XZ, we have:
Point at X = (12, 2)
Point at Z = (6, -2)
Slope, m of XZ = (-2 - 2)/(6 - 12)
Slope, m of XZ = -4/-6.
Slope, m of XZ = 2/3.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by this mathematical expression:
m₁ × m₂ = -1
-1 × 2/3 = -1
-2/3 = -1 (False).

Answer:
Step-by-step explanation:
It is given that the regression equation
predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).
The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.
Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.
and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.
