How does z-axis relate to y-axis and x-axis?
the z axis is at right angles to both the x and the y axis. All 3 axis pass through the origin.
What does reflection over the y-axis mean?
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).
How do you graph x equals 2 and what is its slope?
x=2 means that on a graph, on the x axis, there is a point. Also, since it is just x=2 it means that the slope is undefined, or that there is a line that is going through that point that is perpendicular to the x-axis. So basically there is a line that goes through (2,0) that is parallel to the y-axis.
Is a reflection in the y-axis a vertical or horizontal reflection?
Vertical. Vertical. Vertical. Vertical.
What is the slope of a line that is parallel to the y-axis?
There is none because it will be a straight vertical line cutting through the x axis.
What single transformation is equivalant to a reflection in the y axis followed by a reflection in the x axis followed by another reflection in the y axis?
reflection in the x-axis
Which graph shows a reflection across the x-axis?
y = -f(x) is a reflection of y = f(x) in the x axis.
What is the coordinate of 612 after reflection in x-axis?
The coordinate of a point in 1-Dimensional space will remain unchanged through such a reflection.
Reflection across the x-axis?
In transformations a reflection across the x axis produces a mirror image
How can you reflect figures in the x-axis and y-axis?
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
What does reflection over the x-axis mean?
(x,-y)
How do you find the reflection of a point that is reflected over the x- axis and then over the x- axis?
It will be where it was, to start with.
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 rule for a reflection across the x-axis?
For a reflection across the x axis, both the slope and the y intercept would have the same magnitude but the opposite sign.
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 transformation gives the same result as a rotation of 180 around the origin followed by a reflection over the x axis?
Reflection in the y-axis.
What is the reflection of f of x equals x2 across the x axis?
It is f(x) = -x^2.
