Question

How are lines KL and MN related​

Answer 1

Answer:

The lines KL and MN perpendicular to each other.

Step-by-step explanation:

If a line passes through two points, then the slope of the line is

$m=\frac{y_2-y_1}{x_2-x_1}$

From the given graph it is clear that coordinates of points on line KL are K(-8,2) and L(6,2).

The slope of line KL is

$m_1=\frac{2-2}{6-(-8)}=0$

The slope of line KL is 0, it means it is a horizontal line.

From the given graph it is clear that coordinates of points on line MN are M(-4,8) and N(-4,-6).

The slope of line MN is

$m_2=\frac{-6-8}{-4-(-4)}=\frac{1}{0}$

The slope of line MN is 1/0 or undefined, it means it is a vertical line.

We know that vertical and horizontal lines are perpendicular to each other. Therefore the lines KL and MN perpendicular to each other.

Answer 2

They are straight and are perpendicular
