The easiest way to graph a linear function is to rewrite it in slope-intercept form, y=mx%2Bb.
m represents the slope, rise%2Frun
b represents the y-intercept, x=0
x-y=5
-y=-x%2B5
You always want the y positive, so multiply the whole function by -1
y=x-5
x%2By=3
y=-x%2B3
Now, graph the two lines.
graph%28400%2C400%2C-5%2C5%2C-5%2C5%2Cx-5%2C-x%2B3%29
The answer for your system is where the two lines intersect.
Answer: (4,-1) or x=4 and y=-1
Hope this helps!
