I can find the zeros from a graph, but that won't help you any, because
I'm not about to draw the graph and then post it here.
y = (x + 1) (x - 1)
y = 0 when x = +1 or x = -1.
Ответ:
put a dot backwards 3 squares and up 2 from the center.
then you want to put a dot labeled k that would make a slope 4 squares long (-2, 1)
b doesn't specify how long the slope should be so I would just put a line labeled l and connect that up to j
