Answer:
Step-by-step explanation:
The first step to finding the equation of this line we must find two points that are on this line.
Two points on the lines are (0,3) and (1,0).
Now we must find the slope:

Now after finding the slope which is -3, now let us put it into the point-slope form using the point (0,3) which is also on the line. You could also use (1,0) in this case, but I am using (0,3).

Thus the equation is 
Hope that helps!
