Given ,
ax + 9y = 1
9y - x - 1 = 0
represent same line.
So,
ax + 9y - 1 = 9y - x - 1
ax + 9y - 1 - 9y - 1 = -x
ax = -x
a = -1 .
Therefore, We had equated both given equations as both of them represent same line .
Value of a = - 1
ax + 9y = 1
9y - x - 1 = 0
represent same line.
So,
ax + 9y - 1 = 9y - x - 1
ax + 9y - 1 - 9y - 1 = -x
ax = -x
a = -1 .
Therefore, We had equated both given equations as both of them represent same line .
Value of a = - 1
