give medal and fan, for explain me and give me the answer

OpenStudy (anonymous):

Is the line for the equation x = 4 horizontal or vertical? What is the slope of the line? Select the best answer. A)The line is horizontal. The slope is 0. B)The line is vertical. The slope is undefined. C)The line is horizontal. The slope is undefined. D)The line is vertical. The slope is 0.

OpenStudy (anonymous):

wats up

OpenStudy (anonymous):

Can you help?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

so

OpenStudy (anonymous):

please help me

OpenStudy (anonymous):

So the answer will be A

OpenStudy (anonymous):

A? CAN YOU EXPLAIN WHY?

OpenStudy (anonymous):

If a line is drawn through y = 1, you can plot any points on x but the y point will always be a 1. This makes a straight, horizontal line. The change in y is 0 since y is always 1 and 1-1 = 0. Any fraction with a 0 in the numerator = 0, no matter what number is on the bottom, right? So if there is no change in the rise, the line is horizontal.

OpenStudy (anonymous):

Wow, you can also think of it as whenever a line is equal to x its vertical. and whenever it is equal to y its horizontal?

OpenStudy (anonymous):

can you tell me if the aanswers A its the correct answer? @sunleaf01

OpenStudy (anonymous):

no a is not correct

OpenStudy (anonymous):

can you help me with this to find the answer?

OpenStudy (anonymous):

yeah sure,

OpenStudy (anonymous):

For one the line is vertical

OpenStudy (anonymous):

so, wait the answer its B or D? IM RIGHT?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

Now we need to figure out if its B or D

OpenStudy (anonymous):

HOW?

OpenStudy (anonymous):

its a

OpenStudy (anonymous):

no its not

OpenStudy (anonymous):

yes it is stipid

OpenStudy (anonymous):

im so confused now

OpenStudy (anonymous):

are u in college no your not

OpenStudy (anonymous):

so sunleafe is wrong

OpenStudy (anonymous):

Excuse me, Emily dont listen to them.

OpenStudy (anonymous):

can you continue please

OpenStudy (anonymous):

Open up a graphing calculator and graph the line. Desmos graphing calculator is a great choice.

OpenStudy (anonymous):

its c i thought it was =1 its = 4 its c tho

OpenStudy (anonymous):

WOW NOPE

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

you know the answer? what its the page for the calculator?

OpenStudy (anonymous):

just checked its c retard

OpenStudy (anonymous):

Lol, what college do you go to? Community colledge?

OpenStudy (anonymous):

im not in college

OpenStudy (anonymous):

Not you.. Don't worry about it. Anway, we know that the answer is either B or D, but now we need to figure out wether the slope is zero or undefined.

OpenStudy (anonymous):

Zero slope looks like this: 0/5 Undefined slope looks like this: 5/0

OpenStudy (anonymous):

i think its D? IM RIGHT?

OpenStudy (anonymous):

yup : )

OpenStudy (anonymous):

Good job

OpenStudy (anonymous):

thank you, can you check a question? please and tell me if im right

OpenStudy (anonymous):

yeah sure

OpenStudy (anonymous):

Which of the following lines is parallel to x = 4? 3y = 9 y = 4 x = 2 x = y

OpenStudy (anonymous):

i choose B

OpenStudy (anonymous):

Okay, well we know that the line X=4 is vertical, but...the line y=4 is not horizontal. For a line to be parallel to the line x=4 it needs to follow the format x= ???

OpenStudy (anonymous):

I DONT KNOW, im not good at math ;(

OpenStudy (anonymous):

YEAH YOU ARE!!!!

OpenStudy (anonymous):

LETS THINK THIS THROUGH, WE CAN DO IT!!!1

OpenStudy (anonymous):

okay wait its the answer C?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

THANK YOU SO MUCH
