Question6 : GA -2 

The slope of this line is 3/7 and not (-3/7) as shown in answer.
Can you please check the y2 -y1 did not consider (0-(-3)) = 3;
The lines lines DC and AC are perpendicular.

Please do the needful
Regards
Vidhya

Dear learner,

Kindly check with solution pdf again. Pay attention to the sign of denominator and points you assign for (x1, y1) and (x2, y2) should be clearly mentioned in order to avoid such error.

Thanks and regards
