First, lets break down the sample equation: y=-2x+7
-2=m=slope
+7=b=Y-intercept

Using process of elimination:
A is not perpendicular because the angle created by slopes is unequal to 90
B and D are quadratic equations, and have no correlation with the sample equation
C is parallel to the sample equation

Is there a typo in your question? None of these answers are correct, but I am wiling to keep helping you, I enjoy Algebra.

What is the perimeter, in units, of polygon UVWXYZ? Enter your answer in the box.
nikitadnepr [17]

Given:

Consider the below figure attached with this question.

To find:

The perimeter of the polygon UVWXYZ.

Solution:

All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.

From the figure it is clear that,

UV = 9 units

VW = 2 units

WX = 3 units

XY = 3 units

YZ = 6 units

ZU = 5 units

Now, perimeter is the sum of all the sides.

Perimeter=UV+VW+WX+XY+YZ+ZU

Perimeter=9+2+3+3+6+5

Perimeter=28

Therefore, the perimeter of UVWXYZ is 28 units.
