Question

In order to find the slope of a given straight line, choose two points on the line, separated by a distance ______ the length of the line.

Answer 1

Slope of a straight line

1. In general, the slope of a line gives the measure of its steepness and direction.
2. Mathematically, a slope of a line is the change in $y$ coordinate with respect to the change in $x$ coordinate.
3. If $\left(x_1,y_1\right)$ and $\left(x_2,y_2\right)$ are any two points lying on the line (i.e., the distance between there two points is less than the length of line). Then, the slope of a straight line can be calculated using the formula, Slope $\left(m\right)=\frac{y_2-y_1}{x_2-x_1}$

Hence, the distance between there two points should be less than the length of line.
