The formula for f(x) is f(x) = 1/4(8 - 5x)

How to write a formula for f(x)?

The equation of the function is given as:

-5x - 4y = -8

Add 5x to both sides of the equation

-4y = 5x - 8

Divide both sides both the equation by -4

y = -1/4(5x - 8)

Rewrite the above equation as:

y = 1/4(8 - 5x)

Express the above equation as a function

f(x) = 1/4(8 - 5x)

Hence, the formula for f(x) is f(x) = 1/4(8 - 5x)
