Answer:
The equation of the required line is: 2x + y = 8
Step-by-step explanation:
When a point on the line and the slope of the line are given, we use the slope - one - point form to determine the equation of the line.
Say, 
is the point passing through the line and the slope of the line is say, 
. Then the equation would be:
Here 
and slope, 
.
Therefore, the equation of the line becomes:
Rearranging we get:
which is the required equation of the line.
