## hba 3 years ago If the point (-5,-12) is reflected across the x-axis and then across y-axis,then what are the coordinates of the resulting point ?

1. AERONIK

do you want a method or a direct formula ?

2. hba

Well i need hints ?

3. hba

So the formula and a diag would work @AERONIK

4. AERONIK

so basically take general points h and k, and find the foot of the perpendicular to the line... and then use the argument that the slopes of the line as the mirror and the line joining the 2 points are perpendicular, and you will get the answer...

@AERONIK ok ok i loose,now give me the whole solution :D

6. AERONIK

just give me a line and a point and i will explain it to you in detail, else it will be monotonous..

7. hba

See my ques ?

8. AERONIK

(-5,-12) is in the third quadrant so its reflection along x axis will be in the second quadrant and that will be (-5,12) try finding its reflection now along the y axis, its just changing signs according to the quadrants, is that ok ?

9. hba

so (-5.-12)

10. AERONIK

it will be (5,12) and in the first quadrant. here is a tip, for me reflection with x axis and y axis is same as finding the reflection with respect to the origin....
