Question 351620
The quickest way to graph is to find the intercepts.
To find the x-intercept, set y=0 and solve for x.
{{{x-y=4}}}
{{{x-0=4}}}
{{{x=4}}}
(4,0)

To find the y-intercept, set x=0 and solve for y.
{{{x-y=4}}}
{{{0-y=4}}}
{{{y=-4}}}
(0,-4)

.
Plot the points and connect them with a line.

You can either calculate the slope from the graph {{{m=(DELTA*y)/(DELTA*x)}}} or convert the equation to slope intercept form, {{{y=mx+b}}} where {{{m}}} is the slope.
{{{x-y=4}}}
{{{y=x-4}}}
