It’s A. 9 the equation is y=9x+0
Answer:
x is the input, or independent variable and f(x) is the output, or dependent variable or quantity. f(2) represents the output (y-value) when x = 2. The value of f(2) is 2.
Step-by-step explanation:
If the values of a variable depends on the other variable, then it called dependent variable.
If the value of a variable does not depend on the other, then it is called independent variable.
If a function is f(x)=x, then x is an independent variable and f(x) is a dependent variable.
The given function is
Here, x is the input, or independent variable and f(x) is the output, or dependent variable or quantity.
The notation f(a) represents the output (y-value) when x = a. So, f(2) represents the output (y-value) when x = 2.
Substitute x=2 in the given function.
The value of f(2) is 2.

The two lines meet at (-1,1)
Answer:
3 x $10.50 = $31.50
Step-by-step explanation:
$10.50 + $10.50 + $10.50 = $31.50
$10.00 + $10.00 + $10.00 = $30.00
$0.50 + $0.50 + $0.50 = $1.50
$30.00 + $1.50 = $31.50
