Therefore, the geometric form of the linear function y = -2x + 1, -2≤x≤2 (Figure b)

The line representing the graph of Figure (b) of the questionnaire intersects the positive vertical half-axle at a point with a abscissa positive number and an ordinate positive number and also crosses the positive horizontal half-axle. The ends of the straight line representing the graph of the line have a abscissa -2 and an ordinate positive and abscissa 2 and an ordinate negative, respectively.We also notice that the ordinate of the point to the left of the vertical positive half-axis (fourth quadrant) is the absolute value greater than the ordinate of the point to the right of the vertical half-axis (second quadrant). (Scheme b)Also α = -2 <0, whereby the position of the aligned segment in the ortho-normal coordinate system is determined. Therefore, the geometric form of the linear function y = -2x + 1, -2≤x≤2 (Figure b)
