The form of a function is y = mx + b (with m being the slope and b the point at which the function crosses the y-axis), so you have to isolate the y. To do this, you can first subtract 2x from sides to reach -4y = 4 - 2x, or -4y = -2x + 4; you're practically there already. All you have to do then is divide everything by -4 to obtain y = 1/2 x -1. You have successfully isolated the y and moved the variables to equal the form y = mx + b, so you are done.
