You do know what a "slope field" is, don't you? Pick some values of x and y, calculate for each of those x, y, draw a short line segment centered at (x,y) and with that slope.
This problem is not difficult - just tedious. Start asking yourself questions like, "Where is the slope zero?", "Where is it positive/negative?", etc.
For example, the slope is 1 on the curve or .
Just keep it up until you have what you think is enough slopes to make a slope field.
