Answer :
Example of linear equation:
[tex]y = mx + b[/tex]
Let's have the linear equation;
[tex]y = 2x + 3[/tex]
Put x=1
[tex]y = 2 \times 1 + 3 \\ y = 2 + 3 \\ y = 5[/tex]
[tex](x,y) = (1,5)[/tex]
Put x=2
[tex]y = 2 \times 2 + 3 \\ y = 4 + 3 \\ y = 7[/tex]
[tex](x,y) = (2,7)[/tex]
Put x=3
[tex]y = 2 \times 3 + 3 \\ y = 6 + 3 \\ y = 9[/tex]
[tex](x,y) = (3,9)[/tex]
