Question

Graph the function. xy+4 = 0

Answer 1

hint: solve for "y", graph that

Answer 2

Im not sure how do I put a 0 in for x?

Answer 3

\(\bf xy+4=0\implies xy\cancel{+4-4}=0-4\implies \cfrac{\cancel{x} y}{\cancel{x}}=\cfrac{-4}{x}\)

Answer 4

then it would be the same for the y

Answer 5

sorry i mean x

Answer 6

it's the same function, yes

Answer 7

so i can put any number in for x and y then graph it?

Answer 8

yeap

any random "x" and get a "y value" and graph that
is a LINEar equation, so to graph a line, you only need two points, thus only two "x" values

Answer 9

ahh ok i think i have it now

Answer 10
