Question

parallel, coinciding, or perpendicular?
y=-3
x=6
How do you solve this?

Answer 1

When you see a linear equation with only one variable it means that the "missing" variable can have any value. For y=-3, y is always -3 reagrdless of the value of x. Therefore, the following points would be on it's graph(-7,-3), (101,-3), (5,-3) etc. Therefore it is a horizontal line.

Apply the same logic to x=6, and the answer to the question will be apparent.

Answer 2

i do not understand. Is it coinciding then sense they have the same numbers?

Answer 3

How do vertical and horizontal lines intersect?

Answer 4

perpendicular?

Answer 5

Yes.
