For this case we have that the slope of a line is given by:

Where:
and
are two points through which the line passes.
According to the statement we have to:

Then, the slope of the line is:

By definition, if two lines are perpendicular then the product of their slopes is -1, that is:

We find 

Answer:
The slope of a perpendicular line is:

Answer:
a non linear function to the algrithm
Step-by-step explanation:
magth
Answer:
x = 7
Step-by-step explanation:
12x - 16 = 68
Add 16 to each side
12x - 16+16 = 68+16
12x =84
Divide by 12
12x/12 = 84/12
x = 7
Answer:
perpendicular
Step-by-step explanation:
x = 4 is a vertical line.
y = -2 is a horizontal line.
The lines are perpendicular.
Based on the positions of angles AFC and EFC, the relationship between them is a Complimentary angle.
<h3>How are AFC and EFC related?</h3>
Angles AFC and EFC are complimentary angles because complimentary angles are angles that add up to 90 degrees.
Looking at the shape, Line FC divides the right angle to create angles AFC and EFC so when these are added together, they equal 90 degrees.
In conclusion, angles AFC and EFC are complimentary.
