Question

If the point (8,9) lies on the line ax-5y+13=0, then the value of a is​

Answer 1

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.
