Question

Can somebody please answer this question - Why is slope = tanθ?

Answer 1

Answer:

The slope of a line is positive if it makes an acute angle in the anti-clockwise direction with x-axis. ... (iii) Since tan θ is not defined when θ = 90°, therefore, the slope of a vertical line is not defined. i.e., slope of y-axis is m = tan 90° = ∞ i.e., not defined. (iv) Slope of x-axis is m = tan 0° = 0.
