The slope of an horizontal line is always zero.

This comes from the fact that the slope is given by:

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

and if two points lie on a horizontal line this means that their y components are equals and then the numerator is zero.

Therefore the slope is zero.

Answer:

A, C, D

Step-by-step explanation:

Consider triangles NKL and NML. These triangles are right triangles, because

$m\angle K=m\angle M=90^{\circ}$

In these right triangles:

$\overline{NL}\cong \overline {NL}$ - reflexive property;
$\angle KLN\cong \angle MLN$ - given

Thus, triangles NKL and NML by HA postulate. Congruent triangles have congruent corresponding parts, so

$\overline{KN}\cong \overline{NM}\\ \\\overline{KL}\cong \overline{LM}\ [\text{option D is true}]$

Since

$\overline{KN}\cong \overline{NM},$

then

$7x-4=5x+12\\ \\7x-5x=12+4\\ \\2x=16\\ \\x=8\ [\text{option A is true}]\\ \\MN=KN=7\cdot 8-4=56-4=52\ [\text{option C is true}]$

Option B is false, because KN=52 units.

Option E is false, because LN is congruent KN, not LM

Sara is making a key chain using the bead design shown. What fraction of the beads in her design are either blue or red?

klio [65]

You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
