Step 1. Pick a value for x. It can be anything you like, but 0, 1, or some other small integer usually works well and makes the arithmetic easier. (For this problem, given that the coefficient on y is 5, a multiple of 5 would be a good choice)

Step 2. Substitute that value in place of x in your equation. Do the arithmetic and determine the value of y that results.

Step 3. Take the value of x that you selected for step 1 and the value of y that you calculated in step 2 and form an ordered pair (x,y).

Step 4. Plot the ordered pair from Step 3 on your graph. Remember that the x value is the distance right(+) or left(-) along the horizontal axis and the y value is the distance up(+) or down(-) along the vertical axis.

Step 5. Repeat steps 1 through 4 with a different value for x.

Step 6. Draw a line across your graph that passes through the two points that you plotted.

x+5y=20
5y=-x+20
y=-x/5 +4
x=0, y=4 (0,4)
y=0,x=20
Plot the points and draw the line graph.
