Answer:
Equation of line is given by:
 
  
Step-by-step explanation:
Given points:

Slope of line  
 
where  and
 and  is a point on the line
  is a point on the line 



∴ 
Point-slope equation of line is given by:
 
  
where  is a point on the line and
 is a point on the line and  is slope of line.
 is slope of line.
Using point  and slope
 and slope  point-slope equation of line is given by:
 point-slope equation of line is given by:
 
  
Simplifying.
 
  
Using distribution.
 
  
Subtracting 2 to both sides.
 
  
 
  
Thus, equation of line is
