Question

if the points (5,7) lies on the graph of the equation 5Y =ax-10 then the value of a is​

Answer 1

Step-by-step explanation:

By point (5,7)

X=5 and y=7

And they r zeros of the equation

So the result be =0 that is

Modification of the given equation in the form of

ax-5y-10=0

Substitute 5,7 in the equation

5a-5(7)-10=0

5a-45-10=0

5a-55=0

5a=55

a=55/5

a=11
