What is the rule for finding the reflection of a point over the axis?
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
What is the reflection of (-1-5) across y axis?
The reflection of a point across the y-axis involves changing the sign of the x-coordinate while keeping the y-coordinate the same. In this case, the point (-1, -5) will reflect to (1, -5) across the y-axis. This is because the x-coordinate changes from -1 to 1, while the y-coordinate remains -5.
How do you reflect over x axis when y is negative?
When reflecting a point over the x-axis, you are essentially changing the sign of the y-coordinate while keeping the x-coordinate the same. So, if the original point has coordinates (x, -y), reflecting it over the x-axis would result in the new coordinates being (x, y). This transformation is a fundamental concept in geometry and can be applied to various shapes and figures to create mirror images across the x-axis.
How do you reflect over the x axis when a point is over the x axis already?
Reflecting a point over the x-axis involves changing the sign of the y-coordinate while keeping the x-coordinate the same. If a point is already located over the x-axis, its y-coordinate is positive. When reflecting this point over the x-axis, the positive y-coordinate becomes negative, resulting in the point being located below the x-axis.
What is the y-coordinates of a point where a graph crosses the y-axis?
The y-coordinate of every point on the x-axis is zero.
How does a reflection across the y axis change the coordinates of a point?
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
What is the rule for finding the reflection of a point over the axis?
For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
What point lies on the equation y-3(x 5)?
The given expression is not an equation because it has no equality sign
Do X and y coordinates have same sign?
Sometimes they do, sometimes they don't.It depends upon which quadrant the point is in:In quadrant I they both have the same sign - positive;In quadrant II they have the different signs - x is negative whilst y is positive;In quadrant III they both have the same sign - negative;In quadrant IV they have the different signs - x is positive whilst y is negative;
Which point lies on the line with point-slope equation y - 2 x - 6)?
Without an equality sign the given expression can't be considered to be an equation.
What point lies on the equation y-3(x plus 5)?
The given expression is not an equation because it has no equality sign
What are the coordinates of point A when the shape is reflected over the y-axis?
If a point is reflected about the y-axis then the y co-ordinate remains unchanged but the x co-ordinate changes its sign. Examples : (3,7) after reflection becomes (-3,7) (-2, 5) after reflection becomes (2,5)
How do you know when a graph is not a function?
A function cannot have any value of x mapped to more than one vaue of y. So, if any line parallel to the y-axis meets the graph at more than 1 points it is not a function.
When a polygon reflects across the y-axis how do the coordinates of the points change?
For each coordinate point (x, y), the x-value becomes its opposite. Were it positive, it becomes negative, and vice versa. The y-value remains the same. In other words, each point (x, y) becomes (-x, y).
What conjecture can you make about the location of a point when the sign of the x-coordinate is changed?
It will be at exactly the same distance from the y-axis, but on the other side of it.
What is the table of values for x plus 3y equals 11?
For each of the infinite possible vaues of x, there is a different vaue of y. It is not possible to provide a table with an infinite number of entries.
What point lies on the line with point-slope equation y-25(x-6)?
Without an equality sign the given terms can't be considered to be an equation of a straight line.
