Y = -(1/2)x + 4
y + (1/2)x =4
(1/2)x + y = 4
Multiply both sides by 2
2*(1/2)x + 2*y = 2*4
x + 2y = 8
Option B.
I believe the answer is smaller than
Answer:
A) linear
B) y = x is linear; y = 1/x is non-linear
Step-by-step explanation:
A) The points lie on the same straight line, so the function is linear.
__
B) Any function that has x to a power other than 1 will be non-linear.
linear function: y = x
nonlinear function: y = x^-1 = 1/x
