Question

Is the line for the equation y = 1 horizontal or vertical? What is the slope of this line? Select the best answer.

The line is horizontal. The slope is 0.
The line is horizontal. The slope is 1.
The line is vertical. The slope is undefined.
The line is vertical. The slope is 0.

Answer 1

Whenever you have "y = (some number)" the line will be horizontal. If we had "x = (some number)", then the line would be vertical. This is because no matter what the other axis is, the current axis remains the same. I hope that made a little sense!

Answer 2

Thank you but that bad no sense to me

Answer 3

Basically, if y=1, then draw a line that you can see. At y=1 if you go to 1 on a graph in the y direction, no matter what x is, y will always be 1.

Answer 4

So if x were 500, y would still be equal to 1.

Answer 5

So C!!!

Answer 6

No matter what x is, y is always 1. y measures the vertical height from the x axis. If y is always 1, then all points on the line are at the same height from the x axis. That means it is a horizontal line, parallel to the x-axis with slope zero.

Answer 7

So its not C well darn!

Answer 8

It's A I got it!

Answer 9

Alright. :)
