Question

find coordinates of the point where image of an object kept at point (2,1) is formed wirh respect to the mirror kept along the line x+y-5=0​

Answer 1

Answer:

Hi mate here is ur answer

Step-by-step explanation:

(x1,y1)=(2,1)

ax+by+c=0 ---> x+y+5=0

a=1 b=1 c=5

Let the image of the point be (h,k)

Using formula,

h-x1/a+b = k+y1/a+b = -(ax1+by1+c)/ a+b

h-2/2=k+1/2 =-(2+1+5)/2=-8/2=-4

therefore,

h-2/2=-4

h=-8+2=-6

k+1/2=-4

k=-8-1=-9

Therefore image of the point is (h,k)= (-4,-9)

hope this helps.. pls mark brainlist
