One of the equation of the lines which passes through the point (-2, 3) and equally inclined to the co-ordinate axes is
From the above diagram it is clear that; there are two lines PQ and RS, equally inclined to the co-ordinate axes.
For line PQ: m = tan 45° = 1
and (x1,y1)=(−2,3)
Therefore, its equation: (y–y1)=m(x–x1)
⟹ y–3=1(x+2)
⟹ y−3=x+2
⟹ y = x + 5
For line RS: m = tan (-45°) = -1
and(x1,y1)=(−2,3)
Therefore, its equation: (y–y1)=m(x–x1)
⟹ y–3=−1(x+2)
⟹ y−3=−x−2
⟹ y=−x+1
Therefore, the required equations are y=x+5 and y=−x+1
