See a solution process below:

Explanation:

Substitute some points for x to obtain corresponding values for y. Such as:

x=10 Then y=310=3+10=13 gives: (10,13)

x=5 Then y=35=3+5=8 gives: (5,8)

x=0 Then y=30=3 gives: (0,3)

x=5 Then y=35=2 gives: (5,2)

x=10 Then y=310=7 gives: (10,7)

Now, plot the points and draw a line through the points:

graph{y = 3 - x [-20, 20, -10, 10]}
