To determine the angle of inclination of a line through points
and
, first calculate the slope
using the formula:
Now, the angle of inclination
can be found using
. Therefore:
For the second line that passes through the points
and
(which is not provided), we would find the slope similarly and use the
function to determine the angle of inclination once we have the coordinates of the second point.
For a common mistake, always remember that the angle should be in the right quadrant based on your slope calculation; angles measured from the positive x-axis should reflect whether the slope is positive or negative.
