4. In slope-intercept form, what is the equation of a line perpendicular toy - 2x + 7 that passes

Phoenix [80]

Answer:

y = (-1/2)x + 21/2

Step-by-step explanation:

Given equation:

y - 2x + 7

Coordinates = (5,8)

Find:

Perpendicular equation

Computation:

y = mx + c

y - 2x + 7

y = 2x - 7

So,

m = 2

The negative reciprocal of 2 is -1/2

So,

For,

Coordinates = (5,8)

y = mx + c

8 = (-1/2)(5) + c

8 = -5/2 + c

c = 8 + 5/2

c = 21 /2

So,

y = mx + c

y = (-1/2)x + 21/2

Please answer this question

Y_Kistochka [10]

$\bold{\huge{\underline{ Solution }}}$

Before answering the given question, you should know the difference between polygon and regular polygon. 

Polygon :- It is closed figure constitute of straight line having different measurements and also having varies angles.
Regular polygon :- It is also a closed figure constitute of straight lines which having equal measuresment and all the angles of the given polygon are equal .

There are different types of polygon based on the sides :-

A polygon having 3 sided called triangle ,having 4 sides called quadrilateral ,having 5 sides pentagon and so on.

<h3>Let's Begin :-</h3>

I have thought to make a 4 side polygon that is quadrilateral.

Steps of construction :-

Step - 1 :- Draw a 5 cm line AB horizontally
Step - 2 :- Then , From a point B, Draw a Vertical line of 5 cm and named it BC
Step - 3 :- Then, From a point C, Draw a horizontal line of 5 cm and named it CD
Step - 4 :- Now, join the line AD
Step - 5 :- Measure all the angles form by the 4 sides of the quadrilateral.

Result :-  All the angles are equal that is 90° each.

Conclusion :-  The above figure is square as it is having equal sides and angles.

<h3>Now, we have to find the sum of the angles of the polygon :-</h3>

Here, 

All angles are equal in measure 90°

Therefore, 

The sum of the angles of the given polygon

$\sf{ = 90{\degree} + 90{\degree} + 90{\degree} + 90{\degree} }$

$\sf{ = 180{\degree} + 90{\degree} + 90{\degree} }$

$\sf{ = 270{\degree} + 90{\degree} }$

$\sf{ = 360{\degree} }$

Hence, The sum of the angles of the above polygon is 360° .
