Find the transformed equation of the straight line 2x – 3y + 5 + 0 when the origin is shifted to the point (3, –1) after translation of axes.
Let coordinates of point P change when origin shifts to new coordinates h = 3, k = -1.
Transformation formulas:
x = x' + 3 ⇒ x' = x - 3
y = y' - 1 ⇒ y' = y + 1
Substituting into the given line equation:
2(x' + 3) - 3(y' - 1) + 5 = 0
⇒ 2x' - 3y' + 14 = 0
Therefore, the equation of the straight line in the new coordinate system is:
2x - 3y + 14 = 0
