Note that every y in the table is 4 times the corresponding x value. Thus, the function is y=4x. If x=0, y=0 also. Thus, the line passes thru (0,0).
Put a black dot at (0,0). Next, move your pencil point 1 unit to the right and then from there 4 units up. Put a black dot at (1,4).

Draw a straight line through these 2 black dots.
