Question

determine the slope and the inclination with the positive ​

Answer 1

Answer:

The angle of inclination of a line is the angle made by the line with the positive direction of the x-axis. It is usually measured from the positive x-axis in the anti-clockwise direction. The slope of the line is generally denoted by 'm'. Thus, m = tan θ.

Answer 2

Answer:

Positive slope: This means the angle of inclination θ is such that 0° < θ < 90°. i.e. the angle of inclination is acute. Zero slope: This means the line is parallel to the x-axis. Negative slope: This means the angle of inclination θ is such that 90° < θ < 180°.
