A.

f (x) = –2x – 1








B.

f (x) = –1/2 x – 1








C.

f (x) = –2x + 1








D.

f (x) = 2x – 1

Answer 1

\(y=mx+b\) where \(m = \) slope and \(b\) is where the line crosses the \(y\)-axis

Answer 2

what is the slope of that line?

Answer 3

\(\huge \frac{rise}{run}\)

Answer 4

-2?

Answer 5

it goes over 1 and then down 2

Answer 6

\(\frac{1}{-2}=-\frac{1}{2}=m\)

Answer 7

what is the value when the line crosses the y-axis?
