given:
point (,)
equation of a line:
case 1:
since you have nothing else, I guess you need to prove does this point lie on givren line
...........plug in x and y coordinates of the given point
=> point (,) does not lie on given line
case 2:
you might have to find equation o another line that is parallel or perpendicular to given line and passes through given point
so, if you need to find a line that is parallel to given line and passes through given point, you need
first write your line in slope-intercept form (solve it for ):
=>slope is
since parallel lines have same slope, so far your equation is
.........use point (,) to ind
and, parallel line is:
case 3:
if you need to find a line that is perpendicular to given line and passes through given point,
perpendicular line will have a slope negative reciprocal of the and it is:
.........use point (,) to ind
and, perpendicular line is:
