Answer:
The answer to your question is these lines are not perpendicular.
Step-by-step explanation:
Data
A (4, 2)
B (-1, 4)
slope = m = 4
Perpendicular lines mean that these lines cross and form an angle of 90°. Also, the slope of perpendicular lines is negative reciprocals.
Process
1.- Find the slope of the second line and compare it to the slope given.
slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Substitution
slope = [tex]\frac{4 - 2}{-1 - 4}[/tex]
Simplification and result
slope = [tex]\frac{-2}{5}[/tex]
-2/5 is not a negative reciprocal of 4, so these lines are not perpendicular.
