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.
The point where a line crosses the x-axis is called the x-intercept.

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
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
It will be where it was, to start with.
Reflecting a shape means creating a mirror image of the original shape by flipping it over a line called the reflection axis. This results in an image that is an exact copy of the original, but in the opposite direction. The reflection axis serves as the line of symmetry between the original shape and its reflection.
It is the axis of reflection.
Reflections are congruence transformations where the figure is reflected over the x-axis, y-axis, or over a line.
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.
The point where a line crosses the x-axis is called the x-intercept.

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)
To rotate a figure 180 degrees clockwise, you can achieve this by first reflecting the figure over the y-axis and then reflecting it over the x-axis. This double reflection effectively rotates the figure 180 degrees clockwise around the origin.
Point with y = 0 do not move.
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.
If the coordinates of a point, before reflection, were (p, q) then after reflection, they will be (-p, q).
You put time on the horizontal axis and distance on the vertical axis.
