Does the table represent a linear or nonlinear function?

Answer:
y = -4x + 8 its a negative function but it is linear
Step-by-step explanation:
can you plz markit brainliest
Slope (m) = ΔYΔX= -4
1= -4
θ = arctan( ΔY ) + 360°
ΔX= 284.03624346793°
ΔX = 2 – 0 = 2
ΔY = 0 – 8 = -8
Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353
Equation of the line:
y = -4x + 8
When x=0, y = 8
When y=0, x = 2
