When it says f(x) and x is replaced with a number, it just means replace the x in the equation with that number.

(Simpler) Way to solve using the graph:
Go to where x = -4 (4 spaces right of the center) and look above and below it for the line. Wherever the line is, is the answer. So f(-4) = 2 because when x is -4, the y value is 2.

Example of solving with an equation:
f(3) = 2
f(3) = 2(3)
f(3) = 6

You create an equation for the line, than substitute -4 in to the equation.

3. For the equation-4y = &amp;r, what is the constant of variation? (1 point)<br> ООО<br> 02
alexandr1967 [171]

Answer:

3).

- 4y = 8x \\  \frac{y}{x}  =  \frac{8}{ - 4}  \\  \frac{y}{x} =  - 2 \\ y =  - 2x \\ hence \: constant \: is \:  - 2

4).

y \alpha x \\ y = kx \\ where \: k \: is \: the \: constant \: of \: proportionality \\ when \: y = 24 \: and \: x = 8 \\ substitute \: in \: y = kx \\ 24 = 8k \\ k =  \frac{24}{8}  \\ k = 3 \\ value \: of \: constant = 3

If it was by 10, k = 3 by 10

k = 30

5).

general \: equation \: of \: line  \\ y = mx + c \\ but \: m =  \frac{2}{3}  \: and \: c = 9 \\ substitute \: for \: m \: and \: c \: in \: y = mx + c \\ y =  \frac{2}{3} x + 9 \\ alternatively \\ 3y = 2x + 27
