Answer 2

A point is solution to a equation if when substituted gives the answer as zero.

Equation : 3x + 5y – 8 = 0

( a ) ( 1, 0 )

= 3 ( 1 ) + 5 ( 0 ) – 8

= 3 + 0 – 8

= – 5

( b ) ( 0 , 1 )

= 3 ( 0 ) + 5 (1 ) – 8

= – 3

( c ) ( 1, 1 )

= 3 ( 1 ) + 5 ( 1 ) – 8

= 0

Hence it is a solution of the equation.

( d ) ( 0,0 )

= 3 ( 0 ) + 5 ( 0 ) – 8

= – 8

Hope the solution is clear to you!!
