For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
To find the slope, we need two points, according to the table we have:
The slope is:
Therefore, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:
