The equation that represents the line is:

Step-by-step explanation:
We have to observe the graph to find the points on line
So the points on line are:
(x1,y1) = (4,6)
(x2,y2) = (-2,1)
First of all we have to find the slope

Equation of line is given by:

Putting the value of slope

Putting (4,6) in the equation

Putting the value of b

Hence,
The equation that represents the line is:
