Reflection Across X 2 Formula, The rule for a reflection over the y axis is: (x,y) → (-x, y). It assumes students already have reflected over the x and y axes. Since both x - and y -coordinates are reversed numbers, the reflection is in the line y = x . In matrix form it's a 2x2 matrix that multiplies  Where d = a x 0 + b y 0 + c a 2 + b 2 d = \dfrac{ax_0 + by_0 + c}{\sqrt{a^2 + b^2}} d=a2+b2 ​ax0​+by0​+c​ is the signed distance from point P P P to the line. For a point (x, y), the reflection over the x-axis is (x, -y) — you just flip the sign of the y-coordinate. When you reflect across the line y = x y=x y=x, the x x x- and y y y-values switch places. For a collision algorithm I am developing, I need to find out how to reflect a line over another. Let's write down the coordinates of the triangle. Therefore, we can write the equation for the coordinates of the point P(x,y) reflected across the x-axis as follows. Therefore, the reflected point is simply represented as (y1, x1)  The reflection of a point across the line $$x = -2$$x=−2 is found by keeping the y-coordinate the same and changing the x-coordinate. Step 2: Reflect the  I have an equation of a line: 4x−3y=0. Let S:R2→R2 be reflection through that line, and let P:R2→R2 be projection onto that line. R_(x-axis)(P(x,y)) = P'(x,- y). Step 1: Find the coordinates ( x , y ) of the point to be reflected. The rule for a reflection over the x axis is: (x,y) → (x,-y). (x,y). Comments ; Reflecting shapes over a line. The notation for this reflection would be:  To find the reflection of this point across the line y = x, one need only swap the coordinates.

JEE: How do I find the reflection of a line over another line? Teach the rules for reflecting points over the x x x-axis, y y y-axis, and other lines ( ( (example, ( x , y ) (x, \, y) (x,y) becomes ( − x , y ) (- \, x, \,  This video shows how to reflect over lines like x=3 or y=-2.
