Hello! quick question.
why the line y = 3 is a horizontal line.
describe how this line sits on the Cartesian (coordinate) plane.
I have tried a few thoughts on this. Firstly the horizontal sits on the y intercept. The graph y = b is a horizontal line. 3 is to the left of the origin which is 0. It follows the order of a number line. Negative numbers to the left and positive numbers to the right. This is all I have so far. Did I get close??
Your help is appreciated!!

If you followed a line that has a slant or slope, you'll notice that the
x and y coordinate are both changing.
If you followed a vertical line,only the y coordinate will change.If you
followed a horizontal line, the x co
ordinate only will change. The y co
ordinate will be constant(y = c). Therefore, when x is constant,its' a
vertical line; and when y is constant,
its' a horizontal line.
In your case, y = c = 3, and its' a hor. line. Since y is constant, it re
mains the same no matter what value
you assign to x.
Use the following points to graph the
Eq.: y = 3.
(4 , 3) , (2 , 3) , (0 , 3),
(2 , 3).
I hope this will help.
