Question

Which equation represents the horizontal line passing through (-1,2)?
A.
x = -1
B.
y = -1
C.
x = 2
D.
y = 2

Answer 1

which line is horizontal and which one is vertical
let's get that straight first of all

Answer 2

ummmm idk

Answer 3

y is always horizontal
x is always vertical

Answer 4

We know each of the 4 lines in option a, b, c, and d are straight lines

Answer 5

since we know that y is horizontal and the question wants a horizontal line that passes through the point (-1,2) we know that the line must be one that is y=
Therefore, it must be option B or D

Answer 6

Let's take an example
y = 5
We know that this is a horizontal line that passes through every value of x but it stays on only one value of y, which is 5

Answer 7

basically when it says y = 5 it means y will always equal 5 whatever x is

Answer 8

So we know the point (-1,2) the y component is 2 and it's a horizontal line. So y must = 2 whatever x may be. So, which eqn above does that?

Answer 9

c??

Answer 10

what type of line would c be?
