Answer:
The slope of the line is 
and the equation of the line is 
.
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of 
there is one and only change in 
, fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
(1)
Where:
- Initial and final x-coordinates of the line.
- Initial and final y-coordinates of the line.
If we know that 
and 
, then the slope of the line is:
From graph we conclude that x-intercept of the line is 
. Hence, the equation of the line is and we proceed to plot the expression with the help of a graphing tool.
