Step-by-step explanation:
if any points lies on the graph of some equation then it is a solution of that equation, which means it will satisfy the equation
therefore, substitute (2,3) in the given equation, which gives us a+b=6 ...(i)
then, again for point(-4,-9), -2a-3b=6...(ii)
solving both equations for a and b gives
a=24 and b=-18
