y=6x+5

100

Does the following represent a function? Why or why not?

{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}

No, -1 has two different outputs.

200

What is the slope of the line between (3,-2) (-5.4)

-3/4

200

Does the following represent a function? Why or why not?

No because -2 goes to both 1 and 3.

200

What is the formula for inverse variation?

y=k/x

200

What is f(5)?

f(5) = 4

300
