You know by the form of the equation that the equation is a line.
You also know that all you need to find to plot a line is two points on that line. Find two points, then draw the line that contains them both.
For me, the easiest way to find two points is to make one of the coordinates 0 and then solve for the the other coordinate.
So, let x = 0
Then

one point on the line is (0,3)
Now set y = 0 and solve for x

Another point on the line is (3.75, 0)

Plot those two points and draw a line through them
