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.

What is the equation of the vertical line passing through (-4-5)?
What is the equation of the vertical line passing through (-5,-2)
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.
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.
How did you graph a linear equation in two variables?
By using the formula for a straight line equation graphed on the Cartesian plane by means of the x and y axes.
What graph would best represent the equation y -4x - 6?
If you mean y = -4x-6 then it is a straight line equation that can be graphed on the Cartesian plane
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
What is an equation that forms a line when graphed?
y=mx+b
What is the equation of the vertical line passing through (-4-5)?
What is the equation of the vertical line passing through (-5,-2)
What is Y equals x - 4?
This is the equation of a line in which the slope is 1 and the y-intercept is -4.
What is the slope of the line perpendicular to y5?
I can't tell if you meant to say ' y5 ' or ' y = 5'.-- ' y5 ' is just a number. It can't be graphed, it doesn't represent a line, and the phrase"perpendicular to it" has no meaning.-- ' y = 5 ' is the equation of a horizontal line. Its slope is zero. Any vertical line,with the equation [ x = a number ] is perpendicular to it. The slope of a vertical lineis "undefined" if you want to be mathematically correct, or "infinity" if you don't care.
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.
How do you write an equation with and undefined slope?
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
Is x plus y2 equals 25 a linear equation?
No, not if the y is squared. When graphed the equation will not form a straight line.
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.
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.
