# How do you graph using the intercepts for  x-2y=8?

Mar 18, 2018

$y = \frac{1}{2} x - 4$

#### Explanation:

Recall the formula for a linear equation:

$y = m x + b$

So

$x - 2 y = 8$

$- 2 y = 8 - x$

$y = \frac{1}{2} x - 4$

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

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

$\frac{1}{2} = \text{Rise"/"Run}$

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

Hope this helps. :)
