Y=5x-4 is linear
y=x/3 is linear
y=x^3+1/3 is non linear
Basically linear means it is a straight line when graphed. So anything with exponts is non linear by default among some other rules for determining linear or nonlinear Hope this helps! Please rate my answer and help me also! Thank YOU!!!!!:)
Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
