That's a very nice linear equation in "Standard Form". It's arranged so that the x variable is first with a positive coefficient, the y variable is second and the constant term is on the right side of the equation by itself.
I'm not certain what you want to do with it, but we can put it in "slope-intercept" form where we simply solve it for "y".
In this case start by adding "-11x" to both sides to get:
11x - 20y -11x = 5 - 11x
next, combine the like x terms on the left side:
11x - 11x -20 y = 5 - 11x
-20y = 5 - 11x
divide both sides by -20 to get:
y = 5/-20 -11x/-20
y = (11/20)x - 1/4
This shows that it is a linear equation with a slope of 11/20 and a y intercept of 1/4.
Since it's in slope/intercept form you can enter it in the graph editor using the [y=] key as:
y1 = 11x/20 -1/4
and then press the [GRAPH] key to graph the equation.
