Answer:
4
Step-by-step explanation:
Given, ( 8 , 9 ) lies in the line ax - 5y + 13 = 0 .
This means, if x coordinate of a point lying on the line is 8 and y coordinate is 9. Then the value of ax - 5y + 13 should remain 0.
Thus, now replacing x as 8 and y as 9:
⇒ a( 8 ) - 5( 9 ) + 13 = 0
⇒ 8a - 45 + 13 = 0
⇒ 8a - 32 = 0
⇒ a = 32 / 8
⇒ a = 4
Hence the required value of a is 4.
