The line extends to the first and third quadrants, α> 0. Therefore, its algebraic form is y = αx, where α> 0

The line representing the graph of Figure A of the questionnaire passes from the beginning of the axes, β = 0 (the point crossing the horizontal and the vertical axis of Figure A). The line extends to the first and third quadrants, α> 0. Therefore, its algebraic form is y = αx, where α> 0.
