Question

Write a linear equation. Choose three input values and find the corresponding output values. Show your work.

Answer 1

Example of linear equation:

$y = mx + b$

Let's have the linear equation;

$y = 2x + 3$

Put x=1

$y = 2 \times 1 + 3 \\ y = 2 + 3 \\ y = 5$

$(x,y) = (1,5)$

Put x=2

$y = 2 \times 2 + 3 \\ y = 4 + 3 \\ y = 7$

$(x,y) = (2,7)$

Put x=3

$y = 2 \times 3 + 3 \\ y = 6 + 3 \\ y = 9$

$(x,y) = (3,9)$
