Find the inclination (in radians and degrees) of the line passing through given points
Answer to Problem 27E
The inclination of the given straight line is
Explanation of Solution
Given:
The line passing through the points
Let m be the slope of the line joining the points
The graph of the line connecting given points is
Let
Now, the inclination of the equation is determined from the equation
Now,
As slope of the line is negative, it follows that
Therefore,
And in degrees,
So, the inclination of the given straight line is
