If point p (6,9) is reflected across the line y =2, what are the coordinates of its reflection image

(6,-5)

Step-by-step explanation:

Reflection across the line y = 2 doesn't change the x-coordinate.

The distance between the original point and the line y =2 is equal to the distance between the reflected point and that line. For point (6,9) the y-coordinate is 9, then distance is: 9 - 2 = 7 units . The y-coordinate of a point below the line that is at a distance of 7 units is: 2 - 7 = -5. Therefore, the reflected point is (6, -5)

answer: x

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
