Question

A ( B ) lies on ( 9 n+b y=7 ) eme
5) It must satis fy the bine ( a(3,5) )
( =3 )
( 3(44), 2 a+4 b=7 )
(1) ( x_{3} quad 3 a+12 b=21 )
( 3 a+5 b=127 )
( 7 b=14 )
2)( b=2 )( quad 5 a=1 )
( b=2 )

# If the points A(3,5) and B(1,4) lie on the graph of the line ax+by = 7, find the values of a and b. 20 0 6: Draw the graphs of 2x+y=6 and 2x-y +2 =0. Shade the region bounded by these lines and x-
