DE help: Tangent fields/ Isoclines

I've been working on DE papers for a while now and i don't understand tangent fields of isoclines. I've been told their a pretty easy topic but i just can't find any notes/ videos on the internet to help me get my head round them. If some one could break them down for me or find me some decent notes/ video that would be amazing :smile: If its hard to explain without an example i'm currently stuck on question 3 of this paper.
