Please help, this is timed. 50 points for each answer. What is the difference quotient of f(x)?

I would say B or D.

Step-by-step explanation:

Slope of the line is y = 8, so I used that to give myself a little background information to work with.

(please let me know if one of my choices is correct)

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

1/4 of 84 = 84÷4= 21
