Answers to Questions

How to calculate slope coefficient?

From 2 points A(x1,y1) and B(x2,y2), the slope coefficient of the line or the segment hat passes through points A and B is calculated from the fraction formula : $$ \frac{y2-y1}{x2-x1} $$

Example: Search the slope of an affine function that goes through 2 points (x-axis, y-axis) A(1,2) and B(3,4), is calculating the slope value which is \( \frac{4-2}{3-1} = \frac{2}{2} = 1 \)

What is the slope coefficient of a vertical line?

If a line is vertical then the slope coefficient is infinity \( \infty \).

What is the slope coefficient of an horizontal line?

If a line is vertical then the slope coefficient is \( 0 \). This is sometimes the case of a tangeant or an asymptote.

How to demonstrate that 2 lines are parallel?

Two lines are parallel if and only if their slope coefficients are equal.

How to demonstrate that 2 lines are perpendicular?

Two lines are perpendicular if and only if the product of their slope coeffifients is -1.
