Graph the linear system, either by hand or using a graphing device.
If there is exactly one solution, use the graph to find it. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, enter INFINITELY MANY.)

- x + 1/4 y = - 2     ,,,,,,,,,,,,,1

4x - y = 8              ,,,,,,,,,,,,,2

Now multiplying 1 by 4, then

- 4x + y = - 8

4x - y = 8

0 = 0

Now we find intercepts to graph

For x-intercept, put y = 0

4x - 0 = 8

4x = 8

x = 2

For y-intercept, put x = 2

4(2) - y = 8

8 - y = 8

y = 8 - 8

y = 0

Hence  (x, y) = (2, 0)

And also

For y-intercept, put x = 0

4(0) - y = 8

- y = 8

y = - 8

Now for x-intercept, put y = - 8

4x - (- 8) = 8

4x + 8 = 8

4x = 8 - 8

4x = 0

x = 0

Hence   (x, y) = (0, - 8)

Now the graph is
