I did the math and I think that it's 3.7
Answer:
tangent: y-
= -4(x -
)
Step-by-step explanation:
differentiating

isolating y' to one side and simplifying


when x =
,
y' = 
y' = 
tangent: y-
= -4(x -
)
Answer:
a) It is a line where for every one block right, you go four blocks up. (0, -1) is on the line, because that is the y intercept.
b) 1=4x-1
2=4x
x=1/2
