$y = 1/2x - 4$

Recall the formula for a linear equation:

$y = mx + b$

So

$x - 2y = 8$

$-2y = 8 - x$

$y = 1/2x - 4$

Using the $y$ -intercept of $-4$ , plot this on your graph.

graph{y = 1/2x -4 [-10, 10, -5, 5]}

$1/2 = "Rise"/"Run"$

Continue to plot points on the graph, moving up one value once, and right a value twice.

Hope this helps. :)
