Answer:
The third one.
Step-by-step explanation:
Out of the given choices, the phrase that best describes a nonlinear function is letter A. The area of a circle as a function of the radius. This is because area is calculated through the equation,
A = πr²
All the rest of the choices presents linear functions.
A because 2+2=4 which is simple adding equation
Answer:
slope = 4
y intercept = -4
y = 4x-4
Step-by-step explanation:
The y intercept is -4
The slope is (0,-4) and (1,0)
m = (y2-y1)/(x2-x1)
= (0--4)/(1-0)
= (0+4)/(1-0)
= 4/1
=4
The slope intercept equation is
y= mx+b where m is the slope and b is the y intercept
y = 4x-4
