im learning about contour diagrams in my calculus text but I am totally confused as to how one should start drawing those plots?

for example f(x,y) = x+y

then its supposed to go like

x+y = c

y = -x +c

^^i can see that the slope is 1

but how do i plot this graph?..im told that i should give values to c and plot it...but I am totally confused as to how i should do that (the answer is there too but i donno how they drew the graph/which method they used to draw it)

also I am totally confused as to how one can draw a contour diagram from the data given in a table

table of values for f(x,y) = X^2 - Y^2

i have attached the table here too

thank you
