The independent variable would be x, as it depends on nothing to determine its value. The dependent variable is f(x), as it depends on x to determine its value. This means we plug -4 into x and solve the equation to find f(x).
f(x) = -5(-4) + -4/-2
f(x) = 20 + 2
f(x) = 22
So the answer is C.

Step-by-step explanation:
Answer:
y = 2 - 5/4x
or
y = 2 - 1.25x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. Let's make this equation look more like that by isolating y on one side.
5x + 4y = 8
Subtract 5x from both sides.
4y = 8 - 5x
Divide both sides by 4.
y = 8/4 - 5/4x
y = 2 - 5/4x
Each note book was $2, since he was buying 6 note books and he had 12 dollars left over you can assume he spent 12 dollars and 6*2=12 so we know he spent 2 dollars on each individual book :)
