0 We have that The linear transformation matrix for a reflection across the line y = m x is 1 1 m 2 ( 1 − m 2 2 m 2 m m 2 − 1) So reflection across the xaxis would be 1 1 ( 0) 2 ( 1 − ( 0) 2 2 ( 0) 2 ( 0) ( 0) 2 − 1) = ( 1 0 0 − 1) What are the coordinates of the reflection of the point 3/4 across Y axis?Reflected in the xaxis Solution Required transformation Reflection about x axis, So replace y by y Put y = y and Original equation ==> 2xy3 = 0 After reflection ==> 2x(y)3 = 0 2xy3 = 0 So, image equation of the given equation is 2xy3 = 0 Example 2
Solution If A 3 5 Is Reflected Over The Y Axis What Are The New Coordinates Of A
