Answer:
The equation of the line is  .
.
Step-by-step explanation:
Given the values of the slope and a point of the line, we can derive the equation of the line by means of this formula:
 (1)
 (1)
Where:
 - Independent variable.
 - Independent variable. 
 - Dependent variable.
 - Dependent variable. 
 - Slope.
 - Slope.
 - Coordinates of the given point.
 - Coordinates of the given point.
If we know that  and
 and  , then the equation of the line is:
, then the equation of the line is:



The equation of the line is  .
