How do you make a rule for reflecting a line not over the x or y axis?

Draw a perpendicular from a point to the line of reflection. Extend this [perpendicular] line so as to double its length. This point is the image of the original point. Repeat for all key points of the original shape and then join them together.

A point P has coordinates (3 2). What are its new coordinates after reflecting point P over the x-axis?

What is the point on a coordinate plane where the line crosses over the x axis?
The point where a line crosses the x-axis is called the x-intercept.
What does Rx0 mean?
If it is Rx=0, it means you are reflecting your set of coordinates and reflect it across the x-axis when x=0. So it pretty much is saying reflect it over the y-axi
How do you find the slope of a curve?
a trick to figuring out the slope is "rise over run". basically, you start where the line intercepts the Y-axis and count up to the spot where it intersects the X-axis. then you count over from the Y to the X interception point. that is your slope.
How do you use slope intercept method to make a graph?
y=mx+b...... m is rise over run.... how many points it goes up=rise how many it goes over= run..... use b as the y intercept (where the line crosses the y-axis

What is the line over which a figure is reflected?
It is the axis of reflection.
What is the reflection in Geometry?
Reflections are congruence transformations where the figure is reflected over the x-axis, y-axis, or over a line.
How do the coordinates of a point change when it is reflected over the x-axis?
Reflecting the the x-axis (line y=0) leaves the x-coordinate unchanged and negates the y-coordinate: (x, y) -> (x, -y) For example: (1, 2) -> (1, -2) (3, -4) -> (3, 4)
When reflecting something over the x Axis but there are points already there what can be done if there is a zero for the y coordinate?
Point with y = 0 do not move.
What is the point on a coordinate plane where the line crosses over the x axis?
The point where a line crosses the x-axis is called the x-intercept.
How do you find the coordinates of a quadrilateral after reflecting it over the y axis?
If the coordinates of a point, before reflection, were (p, q) then after reflection, they will be (-p, q).
What is the slope of a line on a graph?
The slope of a line is the change of the y(vertical) axis over the x(horizontal) axis. It is the rate. In the formula y=ax+b the a is the slope.
What is the coordinates for a 2-fold rotation about the x-axis and the y-axis?
This question doesn't seem to make sense. First of all, does the 2-fold rotation mean once about the x-axis, then once about the y-axis?Secondly, rotations are around a point, but reflections are over a line (which is what an axis is)Please edit your question and resubmit.
How do you make and equation on a line in a graph?
The equation for the slope of a linear equation is Y=Mx+b, where m is the slope of the line, (Rise over run) and where B is the Y-intercept. (Where it crosses the Y axis)
What are line graph useful for?
Apex- How one variable effects another
When you can use A line graph?
When plotTing data over time, for example: horizontal axis: fish stock and vertical axis: year (1990-2010).
