if the origin is shifted to the point (3,-1) axes remaining parallel the point (a,-7) lies on the new Y-axis and (3,b) lies on the new X-axis then find a and b

Answer:
a = 3. ; b = -1
since it is said that the point (a, -7) lies on the new Y-axis
the x- cordinate should be equal to three and the y-cordinate can be any real number
and it is also said that (3,b) lies on the new X-axis therefore the y-cordinate should be equal to -1 to satisfy (3,-1) as the new origin.
therefore a = 3 and b = -1

Answer:
Origin (−5,9)
Axes will become, x−axis=>y=9
y−axis=>x=−5
For point (3,b) on x-axis =>ordinate, b=9 (as y=9)
for point (9,3) on y-axis absscicca, a=−5 (as x=−5)
