we need to remember below two forms :- vertical line : x = k horizontal line : y = k
ganeshie8
  • ganeshie8
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...
anonymous
  • 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 ?
anonymous
  • anonymous
vertical
ganeshie8
  • ganeshie8
yes :) so it x value is fixed at 5
ganeshie8
  • ganeshie8
all the points on that line will be like this :- (5, k)
ganeshie8
  • ganeshie8
you can pick any value for k
ganeshie8
  • ganeshie8
since they want 2 points, lets pick two random points :- (5, 1) and (5, 2)
ganeshie8
  • ganeshie8
they both will lie on line x = 5
anonymous
  • anonymous
this is the first question?
ganeshie8
  • ganeshie8
yes
ganeshie8
  • ganeshie8
based on how we did first question, can u try 2nd question ?
anonymous
  • anonymous
no lol this is hard
ganeshie8
  • ganeshie8
its ok :)
ganeshie8
  • ganeshie8
2.Give the coordinates of two points on the line y = -2.
ganeshie8
  • ganeshie8
its a horizontal line, so points on it will be of form :- (k, -2)
ganeshie8
  • ganeshie8
u can pick any value for k, just pick two random values
anonymous
  • anonymous
u pick
ganeshie8
  • ganeshie8
ok, my lucky numbers today are 8 and 2 :) (8, -2) and (2, -2)
ganeshie8
  • ganeshie8
those two points will lie on y = -2 line
ganeshie8
  • ganeshie8
Next, 3.Write the equation of the horizontal line passing through the point (-1, -8).
ganeshie8
  • ganeshie8
read the question, what is it they want ?
anonymous
  • anonymous
the want an equation
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 ?
anonymous
  • anonymous
y=k
ganeshie8
  • ganeshie8
Yes ! since the y coordinate of given point is 8, here the equation of line wud be : y = 8
anonymous
  • anonymous
okay
ganeshie8
  • ganeshie8
4.Write the equation of the vertical line passing through the point (3, 1).
ganeshie8
  • ganeshie8
can u try this ?
anonymous
  • anonymous
i dont know :(
ganeshie8
  • ganeshie8
its fine :) look at my first reply, and can u tell me equation for form of vertical line ?
anonymous
  • anonymous
x=k
ganeshie8
  • ganeshie8
it has to pass thru (3, 1) so, the vertical like wud be, x = 3
ganeshie8
  • ganeshie8
5.Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?
ganeshie8
  • ganeshie8
im sure you can answer this q now, try... :)
anonymous
  • anonymous
virtical
ganeshie8
  • ganeshie8
Yes !
ganeshie8
  • ganeshie8
x=4 is vertical, and tje slope of vertical line is UNDEFINED
anonymous
  • anonymous
ok
ganeshie8
  • ganeshie8
wat about the last question ? :)
anonymous
  • anonymous
horizontal
ganeshie8
  • ganeshie8
awesome !! y = -6 is a horizontal line, and slope of horizontal line is ZERO
ganeshie8
  • ganeshie8
*y=-8
anonymous
  • anonymous
is this it we finishes?
ganeshie8
  • ganeshie8
yes we're done :)
anonymous
  • anonymous
OMG thanks @ganeshie8 you are AMAZING
ganeshie8
  • ganeshie8
aww thnks you're sweet :)
anonymous
  • anonymous
Blushing lol
