Plug your X values into the X spot in each equation and plug in the corresponding Y value into the Y spot in each equation. If the statement is true, then it is a linear relationship. If not, then it is not linear.
EXAMPLE:
y=3x+4
1. Plug it in
0=3(4)+4
2. Solve/Simplify
0=12+4
0=16
3.Is the statement true?
This statement is NOT true because 0 is not equal to 16
4. Answer
This is not a linear equation.

Step-by-step explanation:
Answer:
x=0
x=10
x=24
Step-by-step explanation:
f(x) = -.05x^2 + x +6
The initial value is 6 ( Let x=0 and f(0) = 6)
f(x) = -.05( x^2 -20 x -120)
I plotted the equation and maximum is at x=10 and the zero is at x=25
