Brainliest to whoever gives me the right answer first plssss help

which of the following is not a polynomial identity?

Using the given points, find the slope:

 Slope Equation: m = Δy/Δx

 m = (4 - 0)/(8 -(-8)) ⇒ Solve

 m = 4/16 ⇒ Simplify

 m = 1/4

Using the point-slope equation, solve for the line:

 Point-Slope Equation: y - y1 = m (x - x1)

 Using Point 1 (-8, 0):

 y - 0 = 1/4 (x - (-8))

 y - 0 = 1/4 (x + 8) ⇒ Distribute

 y = 1/4x + 8/4 ⇒ Simplify

 y = 1/4x + 2

y = 1/4x + 2
