Complete Horizontal and Vertical Lines Problems 1. Give the coordinates of two points on the line x = 5. 2.Give the coordinates of two points on the line y = -2. 3.Write the equation of the horizontal line passing through the point (-1, -8). 4.Write the equation of the vertical line passing through the point (3, 1). 5.Is the line with equation x = 4 horizontal or vertical? What is the slope of this line? 6.Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

we need to remember below two forms :- vertical line : x = k horizontal line : y = k

look at first question, we're given line x=5, is it vertical or horizontal ?

we make up a random problem

wat ? dint get u...

OpenStudy (anonymous):

nothing lol i dont underdstand the problem

ganeshie8 (ganeshie8):

lol ok :) 1. Give the coordinates of two points on the line x = 5. it is asking us to give two points on that line

ganeshie8 (ganeshie8):

can u tell me, if x = 5 is horizontal or vertical ?

4 years ago
OpenStudy (anonymous):

vertical

4 years ago
ganeshie8 (ganeshie8):

yes :) so it x value is fixed at 5

4 years ago
ganeshie8 (ganeshie8):

all the points on that line will be like this :- (5, k)

4 years ago
ganeshie8 (ganeshie8):

you can pick any value for k

4 years ago
ganeshie8 (ganeshie8):

since they want 2 points, lets pick two random points :- (5, 1) and (5, 2)

4 years ago
ganeshie8 (ganeshie8):

they both will lie on line x = 5

OpenStudy (anonymous):

this is the first question?

4 years ago
ganeshie8 (ganeshie8):

yes

4 years ago
ganeshie8 (ganeshie8):

based on how we did first question, can u try 2nd question ?

4 years ago
OpenStudy (anonymous):

no lol this is hard

ganeshie8 (ganeshie8):

its ok :)

2.Give the coordinates of two points on the line y = -2.

4 years ago
ganeshie8 (ganeshie8):

its a horizontal line, so points on it will be of form :- (k, -2)

4 years ago
ganeshie8 (ganeshie8):

u can pick any value for k, just pick two random values

4 years ago
OpenStudy (anonymous):

u pick

ganeshie8 (ganeshie8):

ok, my lucky numbers today are 8 and 2 :) (8, -2) and (2, -2)

4 years ago
ganeshie8 (ganeshie8):

those two points will lie on y = -2 line

Next, 3.Write the equation of the horizontal line passing through the point (-1, -8).

4 years ago
ganeshie8 (ganeshie8):

read the question, what is it they want ?

4 years ago
OpenStudy (anonymous):

the want an equation

4 years ago
ganeshie8 (ganeshie8):

Yes, they want an equation of horizontal line passing thru (-1, 8) now look at my first reply, and tell me this :- wats the form of horizontal line ?

4 years ago
OpenStudy (anonymous):

y=k

4 years ago
ganeshie8 (ganeshie8):

Yes ! since the y coordinate of given point is 8, here the equation of line wud be : y = 8

4 years ago
OpenStudy (anonymous):

okay

ganeshie8 (ganeshie8):

4.Write the equation of the vertical line passing through the point (3, 1).

4 years ago
ganeshie8 (ganeshie8):

can u try this ?

4 years ago
OpenStudy (anonymous):

i dont know :(

4 years ago
ganeshie8 (ganeshie8):

its fine :) look at my first reply, and can u tell me equation for form of vertical line ?

4 years ago
OpenStudy (anonymous):

x=k

4 years ago
ganeshie8 (ganeshie8):

it has to pass thru (3, 1) so, the vertical like wud be, x = 3

4 years ago
ganeshie8 (ganeshie8):

5.Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?

4 years ago
ganeshie8 (ganeshie8):

im sure you can answer this q now, try... :)

virtical

4 years ago
ganeshie8 (ganeshie8):

Yes !

4 years ago
ganeshie8 (ganeshie8):

x=4 is vertical, and tje slope of vertical line is UNDEFINED

4 years ago
OpenStudy (anonymous):

ok

ganeshie8 (ganeshie8):

wat about the last question ? :)

4 years ago
OpenStudy (anonymous):

horizontal

4 years ago
ganeshie8 (ganeshie8):

awesome !! y = -6 is a horizontal line, and slope of horizontal line is ZERO

4 years ago
ganeshie8 (ganeshie8):

*y=-8
