Question

examine whether the point (1,-2)lies on the graph of the equation 3x-2y=7​

Answer 1

Answer:

it will lie on the graph because when we put the value of x and y name then the RHS is equal to LHS

Answer 2

$Given \:linear \:equation \: in \:two \: variables:\\3x-2y=7$

$Substituting \: x = 1 \:and \:y = -2 , \: in \:the \\equation , we \:get$

$3\times 1 - 2\times (-2) = 7$

$\implies 3 + 4 = 7$

$\implies 7= 7 \: \pink { ( True ) }$

Therefore.,

$\green {Point \: (1,-2) } \: lies \: on \:the \\ graph\: of \:the \: equation \: 3x - 2y = 7$

___________***

Draw the line 3x - 2y = 7 on the graph , we observe the point A(1,-2) lies on the line .
