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 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.
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.
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.
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.
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.
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.
What is the equation of the vertical line that passes through the point 0-4?
The equation of a vertical line passing through the point (-4,0) is x = -4. Since all points on a vertical line have the same x-coordinate, the equation is simply x = -4.
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.
