*(The first order pair)*
[tex]y=-9(0)+3[/tex] Substitute [tex]0[/tex] to [tex]y=-9(0)+3[/tex]
[tex]y=0+3[/tex] Multiply [tex]-9[/tex] to [tex]0[/tex]
[tex]y=3[/tex] Add [tex]3[/tex] to [tex]0[/tex]
*(Answer)*= [tex](0, 3)[/tex]
*(The second order pair)*
[tex]y=-9(3)+3[/tex] Substitute [tex]3[/tex] to [tex]y=-9(3)+3[/tex]
[tex]y=-27+3[/tex] Multiply [tex]-9[/tex] to [tex]3[/tex]
[tex]y=-24[/tex] Subtract [tex]3[/tex] to [tex]-27[/tex]
*(Answer)*= [tex](3, -24)[/tex]
*(The third order pair)*
[tex]30=-9x+3[/tex] Substitute [tex]30[/tex] to [tex]30=-9x+3[/tex]
[tex]27=-9x[/tex] Subtract [tex]3[/tex] to [tex]30[/tex]
[tex]x=-3[/tex] Divide [tex]-9[/tex] to [tex]27[/tex]
*(Answer)*= [tex](-3, 30)[/tex]
