You have selected to grapy inequality and the solver is returning the graph.
All you need to do is read the points of the graph to be able to graph it yourself.

One point is (0, 6) and another (4, 7).

You can also calculate the points if you plug into y = (1/4) x+6

For x = 0, we get y = (1/4)*0 + 6, that is y = 6

For x = 4, we get y = (1/4)*4 + 6, that is y = 7
