Is a vertical line a relation?
Yes it is, but it is not a function.
Why is x equals equals 4 a vertical line?
That would be because all the graphed values of x are 4. So you can plug anything in for Y and it will still be on that vertical line.
What is a linear equation with a undefined slope?
A linear equation with an undefined slope is an equation where, when graphed, forms a vertical line. For example: when given 2 points: (2, 4) (2,7) ~ The x-values are the same, while the y-values differ, which would create a vertical line when the points are graphed
The flashing vertical line that indicates where the next action will occur?
it will be default or highlight because the clue word was flashing vertical lines that indicates
The graph of a relation must pass the vertical line test?
True
What is a mere relation?
A relation is an expression that is not a function. A function is defined as only having one domain per range, meaning that when graphed, a function will have no two points on the same vertical line. If your expression is graphed and two points do appear on the same vertical line, it is a relation, not a function.
What equation is graphed as a vertical line?
Vertical lines only intersect the x-axis. This means that the equation of a vertical line is x=n. The variable n is the coordinate where on the x-axis the line goes.

Why is x equals equals 4 a vertical line?
That would be because all the graphed values of x are 4. So you can plug anything in for Y and it will still be on that vertical line.
Why the line x 4 is a vertical line?
When x = 4 is graphed in an xy plane, it is easy to see why a vertical line is formed. At every value of y, x = 4. Plot enough points like this on your graph and you will soon form a vertical line.
How can you tell if a graph that represents the relationship is a function?
The vertical line test! Imagine a vertical line going through all points of the graph. As long as the vertical line only touches the graphed line once, it's a function. If it touches more than once, it is not.
Why is y equals -8 a function?
y = -8 is a function because when graphed, it passes the vertical line test.
What is the only type of line that is not a function?
A vertical line. Remember that one test to see if a relation is a function is the vertical line test. A vertical line would fail that of course.

A vertical line that indicates the end of a measure?

Which of the following would offer proof that a relation is a function?
a vertical line
