First, convert both of the equations to slope-intercept form
M being the slope and b being the y intercept (0,b)
First equation.

Add 2y to both sides.
=
Next subtract 4 from each side.
=
Now divide each side by 2 to isolate the y variable.
=
Now repeat the process for the second equation.

Subtract x from both sides
=
Now divide both sides by 2 to isolate the y variable
=
Now that both equations are in Slope-intercept form, graph the y intercept of each and use the slope to graph a second point. Compare the graphs of the two equations. Note that they intersect at one point only. This means that the 2 equations have one unique solution and are classified as independent.
