Question

Ellen thinks that if a line has no slope, then it never touches the y-axis. Which line proves that her statement is incorrect?
x = 0
y = 0
x = 1
y = 1

Answer 1

It x=0

Answer 2

y = 0

These represent the x-axis whose slope is 0 and intersects the y-axis at the beginning.

Answer 3

x=0
This is a line which is vertical, and <u>is</u> the y-axis.
It has a slope which is undefined.
So pick which answer reflects your idea of "no slope."

Answer 4

So it's y or x = 0?

Answer 5

If there is no difference in the x-axis, it becomes undefined, or vertical. But, if there is a difference in the y-axis, or if it is zero, it becomes horizontal. I put it down to two choices: x = 0 and y = 1. The y-axis would have been touched if it had been brought to 1. x=0 doesn't do anything about the y-axis, but it makes it vertical. And, what it looks like to other people, choose x = 0.

Answer 6

It is x = 0. I did the test
