Question

If the angle made by the line with positive direction of X-axis is 30° then slope of the line is​

Answer 1

Step-by-step explanation:

Thus, if a line makes an angle θ with the positive direction of the x-axis, then its slope will be tan θ. The slop of a line is positive or negative according as θ is acute or obtuse. Sine a line parallel to x-axis makes an angle of 0° with x-axis, therefore its slope is tan 0° = 0..
