Match the following equations with their direction field. Clicking on each picture will give you an enlarged view. While you can probably solve this problem by guessing, it is useful to try to predict characteristics of the direction field and then match them to the picture. lere are some handy characteristics to start with -- you will develop more as you practice. A. Set y equal B. Do the same for the y-axis by setting z equal to 0 C. Consider the curve in the plane defined by setting y'= 0 -- this should correspond to the points in the picture where the slope is zero. D. Setting y' equal to a constant other than zero gives the curve of points where the slope is that constant. These are called isoclines, and can be used to construct the direction field picture by hand. с D A B zero and look at how the derivative behaves along the x-axis. 1.-2+2-y 2. ye+2y 3. y' = 4. y = y +2 (2x+y) (2y)

Question

I used desmos for this question. And for dy/dx =y+2, none of these four can fit into the slope field. Please explain and answer. Thank you!
