Answer:(-1,-1)
Step-by-step explanation: given line equation x/a+y/b=1 and passes through (2,-3), (4,-5)
Line passes through the point (2,-3) is
= 2/a-3/b=1
=2b-3a=ab----i
Line passing through the point (4,-5) is
=4/a-5/b=1
=4b-5a=ab----ii
Form i &ii
2b-3a=4b-5a
5a-3a=4b-2b
2a=2b
a=b
By substituting the values we get a=b=-1
